description: Here we present a cost effective multi-channel opto-mechanical switch and software PID system for locking multiple lasers to a single channel commercial wavemeter. The switch is based on a rotating cylinder that selectively transmits one laser beam at a time to the wavemeter, the wavelength is read by the computer and an error signal is output to the lasers to correct wavelength drifts every millisecond. We use this system to stabilise 740 nm (subsequently frequency doubled to 370 nm), 399 nm and 935 nm lasers for trapping and cooling different isotopes of Yb+ ion. We characterize the frequency stability of the three lasers by using a second, more precise, commercial wavemeter. We also characterise the absolute frequency stability of the 740 nm laser using the fluorescence drift rate of a trapped 174Yb+ ion. For the 740 nm laser we demonstrate an Allan deviation, df/f, of 3 x 10^-10 (at 20 s integration time), equivalent to sub-200 KHz stability.

description: Η παρούσα διπλωματική εργασία έχει στόχο να παρουσιάσει την σημασία της ηλικίας στην λήψη επενδυτικών αποφάσεων, και τον τρόπο με τον οποίο οι επενδυτές βελτιστοποιούν τα χαρτοφυλάκιά τους. Αρχικά περιγράφεται η σημασία της ηλικίας μέσω της έρευνας βιβλιογραφίας, με την χρήση μαθηματικών μοντέλων. Στα μοντέλα, γίνεται η υπόθεση ότι ο επενδυτής μπορεί να επενδύσει σε δύο περιουσιακά στοιχεία, μετοχές και ομόλογα. Η θεωρία υποστηρίζει ότι όταν οι επενδυτές μεγαλώνουν ηλικιακά αυξάνεται η αποστοφή τους στον κίνδυνο, και θα διαμορφώνουν τα χαρτοφυλάκιά τους με λιγότερες μετοχές, λόγω του υψηλού κινδύνου. Στην συνέχεια, γίνονται αναλύσεις ευαισθησίας για την σημασία του ανθρώπινου κεφαλαίου στην βέλτιστη κατανομή μετοχών στο χαρτοφυλάκιο, καθώς και για τον εργασιακό χρόνο του επενδυτή. Στο τέλος πραγματοποιούνται προσομοιώσεις, και λύνονται ασκήσεις με σκοπό να υπολογιστεί η αναμενόμενη χρησιμότητα του επενδυτή, για διαφορετικές κατανομές μετοχών στο χαρτοφυλάκιο, ώστε να εξεταστεί η σημασία της συσχέτισης μεταξύ των αποδόσεων των μετοχών και του εισοδήματος εργασίας.

description: This dissertation answers some of the questions raised in Borcherds' papers on Moonshine and Lorentzian reflection groups. We prove (assuming an open conjecture of Burger, Li and Sarnak) that a Lorentzian reflection group with Weyl vector is associated to a vector-valued modular form. This result allows us to establish a folklore conjecture that the maximal dimension of a Lorentzian reflection group with Weyl vector is 26. In the case of elementary lattices, we show that these vector-valued forms can be obtained by inducing scalar-valued forms. This allows us to explain the critical signatures which occur in Borcherds' work. Many of the structures which occur at these critical signatures are especially beautiful and have appeared independently throughout the literature. We investigate Borcherds-Kac-Moody (BKM) algebras with denominator formulas that are singular weight automorphic forms. The results of these investigations suggest that all such BKM algebras are related to orbifold constructions of vertex algebras and elements of the Monster sporadic group. Finally, we show how work in this dissertation combined with results of Bruinier gives a new insight into the arithmetic mirror symmetry conjecture of Gritsenko and Nikulin.

description: We carried out optical spectroscopic observations of the most enigmatic dwarf nova WZ Sge in 11 nights during the 2001 superoutburst. Our observations covered the period from the initial phase, several hours before the maximum, to the ninth maximum of the rebrightening phase. The first spectrum shows absorption lines of H I (except for Halpha), He I, and Na I, as well as emission lines of He\II, C III/N III, and Halpha in doubly-peaked shapes. The same spectrum shows the emission lines of C IV and N IV which are the first detection in dwarf novae. The spectral features dramatically changed in various time scales. For example, the peak separations of the emission lines of H I and He II changed from ~700 km/s to 1300 km/s, and one of the peaks dominated over an orbital period in the genuine-superhump era, but the dominant peak interchanged with the orbital phase in the early-superhump era. The lines of H I and He I were in emission at minima of the rebrightening phase (with no high-excitation lines, nor Na I), while they became in absorption at maxima. We report on these observational results in detail and their implications concerning the outburst mechanism, two types of superhumps, and variation of the disk structure.

description: The density variations in thin stellar streams may encode important information on the nature of the dark matter. For instance, if dark matter aggregates into massive sub-halos, these perturbers are expected to scatter stars out of dynamically cold stellar streams, possibly leading to detectable gaps in those structures. Here we re-examine the density variations in the GD-1 stream, using Gaia DR2 astrometry, Pan-STARRS photometry, together with high precision radial velocities measured with the CFHT/ESPaDOnS and VLT/UVES instruments and complemented with public radial velocity catalogs. We show that after correcting for projection effects, the density profile exhibits high contrast periodic peaks, separated by $2.64\pm0.18$ kpc. An N-body simulation is presented that reproduces this striking morphology with simple epicyclic motion in a smooth Galactic potential. We also discuss the reliability of measuring density variations using ground-based photometric surveys, and for the particular case of GD-1 we highlight some of the artifacts present in the Gaia DR2 catalog along its track. Massive dark subhalos do not appear to be required to explain the density clumping along GD-1.

title: The Role of the Polyunsaturated Aldehydes in the Physiology and Ecology of Diatoms
Creators: name: Ribalet, Franҫois
Publisher: name: The Open University
Year: 2007

description: In the last decade diatoms have been shown to release a wide range of secondary metabolites, such as polyunsaturated aldehydes (PUAs), produced by a wound-activated mechanism. PUAs are highly reactive molecules that in most cases induce a drastic reduction in the reproductive response of predators, such as copepods.

The variable toxicity of diatoms observed in nature suggests a modulation of PUA production by environmental factors. My results indicate a strong dependence of PUA production on culture age, nutrient limitation and other stress factors, such as UV exposure and low light conditions, in cultures of Skeletonema marinoi, suggesting a direct link between toxin production and cell physiological state.

Since it has been hypothesized that PUAs may be released in seawater also as a result of cell mortality, phytoplankton lysis rates were estimated during four oceanographic cruises conducted during periods of diatom blooms in the Northern Adriatic Sea. High lysis rates were observed and preliminary results indicated substantial amounts of PUAs released in seawater. The effects of dissolved PUAs were therefore investigated on organisms other than predators, such as co-occurring bacteria and phytoplankton in culture. PUAs are toxic for several phytoplankton species at concentrations well within the range potentially produced by diatoms. Diatoms can be immunized by sub-lethal concentrations of PUAs. In this case, PUAs may act as signal molecules for bloom termination. PUAs induce also different effects on bacterial growth; some strains are inhibited while others show remarkable resistance to these compounds, and a few of them were even stimulated.

Therefore, PUAs appear to have multiple functions in diatoms, namely as chemical defense against grazers, allelochemicals against phytoplankton and bacteria, and signal molecules within their populations.

description: A prior study by one of the authors (Gritta, et. al. 2006) published in the Journal of the Transportation Research Forum, examined the extent of operating, financial, and total leverage facing the major U.S airlines, those carriers with total revenues of $1.0 billion or more. The study found that the vast majority of the carriers were highly leveraged at both the operating and financial levels and that this resulted in highly unstable profitability and increased the dangers of bankruptcy. The global airline industry has always been highly cyclical and somewhat fixed-cost driven. Airlines are thus high in what financial analysts refer to as operating leverage. In addition, the many airlines have followed aggressive debt strategies; that is, they have chosen to use large amounts of long-term debt finance to purchase assets. This results in a high degree of financial leverage. In the past, the resulting combined leverage has created severe financial problems for major carriers, both domestically and internationally. The current study seeks to examine a sample of foreign carriers in order to measure the extent of risks on the international level. In doing so, comparisons will be made to the large U.S. carriers. If possible, the authors will use the same time horizon as in the published paper, although in some cases carriers are too new to have such a history.

Ως αποτέλεσμα, αυτό που διέπει τη ρευστότητα των τραπεζών έχει αλλάξει σε ρυθμιστικό και εποπτικό επίπεδο. Χρησιμοποιώντας τις τέσσερις μεγαλύτερες τράπεζες όσον αφορά την κεφαλαιοποίηση από τις δύο βασικές χώρες της Ευρωζώνης, τη Γαλλία και τη Γερμανία, και δύο άλλες χώρες από την περιφέρεια, την Ιταλία και την Ισπανία, εκτιμούμε ένα μοντέλο που χρησιμοποιεί δεδομένα πίνακα για τον προσδιορισμό των βασικών μοχλών της κεφαλαιακής επάρκειας. Δεν καταφέραμε να εντοπίσουμε καμία μεταβλητή που επηρεάζει τον δείκτη κεφαλαιακής επάρκειας για ολόκληρη την περίοδο. Καθώς το δείγμα περιέχει τόσο την οικονομική κρίση του 2008 όσο και την ευρωπαϊκή κρίση χρέους, εξετάζουμε την παραπάνω σχέση μετά τη δήλωση του Mario Draghi’s “whatever it takes”. Εκτιμώντας το μοντέλο μας από το 2013 έως το τέλος για να ανιχνεύσουμε την επίδραση της απεριόριστης ποσοτικής χαλάρωσης που δόθηκε στο σύστημα, βρίσκουμε ότι οι λόγοι των συνολικών ιδίων κεφαλαίων και καθαρών δανείων προς το σύνολο των περιουσιακών στοιχείων επηρεάζουν το δείκτη κεφαλαιακής επάρκειας. Τέλος, λόγω των πακέτων στήριξης και των ενεργειών ενοποίησης των ισολογισμών των τραπεζών, καταλήγουμε στο συμπέρασμα ότι η β - σύγκλιση επιτυγχάνεται για τον λόγο κεφαλαιακής επάρκειας του επιλεγμένου ομίλου τραπεζών.

description: The main goal of this research was to evaluate how travel time reliability (TTR) might be associated with crashes involving elderly drivers, defined as those age 65 and above. Several TTR metrics were used to estimate their influence on elderly crash frequency and severity of the crash on freeways and arterial highways. The results suggest that TTR is statistically significant in affecting both elderly crash frequency and the severity of a crash involving an elderly driver. In particular, the analysis of risk ratios illustrates that a one-unit increase in the probability of congestion reduces the likelihood of the elderly severe crash by 22%.

description: Lewis Mathieson was my great uncle. He was the youngest of four brothers, the eldest brother being my grandfather, James Mathieson. Lewis followed his three brothers into the Gordon Highlanders, enlisting on 17th August 1903. He served in India and was discharged into the reserve on 6th January 1912. Please see the biography of Lewis that I have written for the story of Lewis in the First World War, his desertion from the army, his subsequent enrolment into the Royal Navy Reserve and his participation in the Battle of Jutland. The story is briefly summarised below.

On the outbreak of the First World War Lewis was mobilised into the 1st Battalion of the Gordon Highlanders and by Sunday 23rd August the Gordons were in position south-west of Mons. In 1915 Lewis was invalided home with frostbite in both feet. He was successfully treated. He reported fit for duty but then decided he would soldier no more and deserted. However, on 30th July 1915 Lewis joined the Royal Navy Reserve using the alias, Alexander Wood, and taking the rating of Stoker. After training he joined HMS Malaya on 28th January 1916. He took part in the Battle of Jutland and received good assessments, Superior for ability and Very Good for conduct.

Lewis Mathieson was awarded the 1914 Star with clasp, the British War Medal and the Victory Medal in spite of being a deserter, the latter two awards being authorised by the Admiralty in respect of service of Wood A.
title: Experiencing Access: Issues for Policy and Practice - A Case Study
Creators: name: Phillips, Paul Robert
Publisher: name: The Open University
Year: 2009

description: The study explores the experiences of Access to Business students on a course that is characterised as diverse in terms of age, ethnicity and nationality. The key research question asked how students from diverse backgrounds experience learning on an Inner-City Access course. Sub-questions explored the extent to which the course attracted students from groups under-represented in higher education, how a classroom characterised as diverse affected the formation and functioning of learning communities and attitudes towards student dropout. I adopted an interpretive, naturalistic method of enquiry, theorising the Access to Business programme as a bounded system (Smith, 1978) and conducting a qualitative case study. From a review of the literature I develop a theoretical framework incorporating habitus and capital (Bourdieu, 1984); communities of practice (Lave & Wenger, 1991; Wenger, 1998) and the relationship between commitment and student dropout (Tinto, 1975). A common thread running through the framework is that of identity and difference. The main research method I employed was the semi-structured interview. Other methods included focus groups, questionnaires and meetings. As a teacher/researcher I was also able to draw on my experience of teaching the students that provided the research data. The main findings of my research reveal the way aspects of identity help to shape the way the classroom functions as a learning community: age, age difference, ethnicity, nationality and attitudes towards study play a part in the way students interact and form groups in the classroom. Diversity is seen as a resource that others can draw on to support learning. The study revealed the way the course has, to an extent, been colonised by those who have social resources that normalise participation in higher education and how aspects of learners' identities influence attitudes towards student dropout. I suggested that the Access to Business course at Inner-London College could do more to target under-represented groups in and that a practical strategy would be to integrate Access awareness raising and normalising activities into existing programmes such as 'Aimhigher'. I also considered how practitioners could improve practice by recognising the importance that identity and social participation plays in learning and suggested practical suggestions for the classroom. Finally I considered possible areas for further research.

description: U.S. airlines have a vested interested in the intentions and purchase behavior of their domestic airline passengers, especially their willingness to pay for assorted ancillary services. For this research, antecedents to purchase intention and actual purchase behavior of airline ancillary services were evaluated using logistic regression and generalized linear model (GLM) and data collected from Amazon Mechanical Turk. The results show differences in airline passenger preferences when purchasing ancillary services. The number of times a passenger flies per year and the trip purpose are significant, while age and gender are not.

description: We present a detailed experimental study of the velocity distribution of atoms cooled in an optical lattice. Our results are supported by full-quantum numerical simulations. Even though the Sisyphus effect, the responsible cooling mechanism, has been used extensively in many cold atom experiments, no detailed study of the velocity distribution has been reported previously. For the experimental as well as for the numerical investigation, it turns out that a Gaussian function is not the one that best reproduce the data for all parameters. We also fit the data to alternative functions, such as Lorentzians, Tsallis functions and double Gaussians. In particular, a double Gaussian provides a more precise fitting to our results.

description: Imaging with sub-wavelength resolution using a lens formed by periodic metal-dielectric layered structure is demonstrated. The lens operates in canalization regime as a transmission device and it does not involve negative refraction and amplification of evanescent modes. The thickness of the lens have to be an integer number of half-wavelengths and can be made as large as required for ceratin applications, in contrast to the other sub-wavelength lenses formed by metallic slabs which have to be much smaller than the wavelength. Resolution of $λ/20$ at 600 nm wavelength is confirmed by numerical simulation for a 300 nm thick structure formed by a periodic stack of 10 nm layers of glass with $ε=2$ and 5 nm layers of metal-dielectric composite with $ε=-1$. Resolution of $λ/60$ is predicted for a structure with same thickness, period and operating frequency, but formed by 7.76 nm layers of silicon with $ε=15$ and 7.24 nm layers of silver with $ε=-14$.

description: In this work, we investigate hole spin-flip transitions in a single self-assembled InGaAs/GaAs quantum dot. We find the hole wave functions using the 8-band $kp$ model and calculate phonon-assisted spin relaxation rates for the ground-state Zeeman doublet. We systematically study the importance of various admixture- and direct spin-phonon mechanisms giving rise to the transition rates. We show that the biaxial and shear strain constitute dominant spin-admixture coupling mechanisms. Then, we demonstrate that hole spin lifetime can be increased if a quantum dot is covered by a strain-reducing layer. Finally, we show that the spin relaxation can be described by an effective model.

description: Starting in the 2013-14 crop year, a lack of export capacity resulted in substantial increases in the spread between farm and port FOB prices in western Canada. This created a very difficult situation for the farming community. We calculate that this situation reduced grain farmers’ income over the 2013-14 and 2014-15 crop years by approximately C$6.7 billion. Clearly, the grain handling and transportation system has problems and capacity to move grain is one of them. To evaluate the need for grain export capacity expansion, we forecast future grain production using a rational expectations model to estimate future export spreads and subsequent rents. We find that without capacity improvements, the expected cost of limited grain export capacity could exceed C$5.6 billion over the next decade. Capacity improvements on the order of a 25% increase will likely mitigate this issue in the future.

description: We study the Friedmann-Robertson-Walker model with phantom fields modelled in terms of scalar fields. We apply the Ziglin theory of integrability and find that the flat model is nonintegrable. Then we cannot expect to determine simple analytical solutions of the Einstein equations. We demonstrate that there is only a discrete set of parameters where this model is integrable. For comparison we describe the phantoms fields in terms of the barotropic equation of state. It is shown that in the contrast to the phantoms modelled as scalar fields, the dynamics is always integrable and phase portraits are constructed. In this case we find the duality relation.

description: Virtual reality (VR) enables data visualization in an immersive and engaging manner, and it can be used for creating ways to explore scientific data. Here, we use VR for visualization of 3D histology data, creating a novel interface for digital pathology. Our contribution includes 3D modeling of a whole organ and embedded objects of interest, fusing the models with associated quantitative features and full resolution serial section patches, and implementing the virtual reality application. Our VR application is multi-scale in nature, covering two object levels representing different ranges of detail, namely organ level and sub-organ level. In addition, the application includes several data layers, including the measured histology image layer and multiple representations of quantitative features computed from the histology. In this interactive VR application, the user can set visualization properties, select different samples and features, and interact with various objects. In this work, we used whole mouse prostates (organ level) with prostate cancer tumors (sub-organ objects of interest) as example cases, and included quantitative histological features relevant for tumor biology in the VR model. Due to automated processing of the histology data, our application can be easily adopted to visualize other organs and pathologies from various origins. Our application enables a novel way for exploration of high-resolution, multidimensional data for biomedical research purposes, and can also be used in teaching and researcher training.

description: Innovation Platforms (IPs) are gaining popularity as a practical approach to operationalizing Agricultural Innovation Systems (AIS) thinking to accelerate agricultural development and poverty eradication particularly in developing countries. The strength of IPs lies in the multi-stakeholder interactions to learn together and co-create knowledge and innovations in the agricultural value chains. Multi-stakeholder interactions are characterized by power relations and influence requiring individual actors to deploy their social and communicative competences to utilize the space provided by IPs to influence benefits from their engagement. In current practice, IPs focus on creating space for multi-stakeholder interaction and little attention is given to building the essential competences for stakeholder groups to take advantage of the opportunities in IPs. Using a case of IPs initiated by the Research-Into-Use (RIU) project in Rwanda, this paper identifies a range of competences required by various stakeholder groups and perceived priorities for capacity strengthening. All stakeholder groups recognize social and communicative competences as necessary to foster interaction in IPs, but downplay their need for capacity strengthening. Instead, they perceive technical competences such as utilizing technologies and business skills to be priority for capacity strengthening. This suggests that for IPs to be successful and sustainable, actors will need greater exposure to the importance of the social and communicative competences. This includes engagement of innovation brokers in training and exposure of actors to communicative skills to equitably gain from the IPs.

description: Current outreach models for universities have been shown to be weak globally. This paper looks at an alternative, less expensive approach which can reach farmers in real time. It describes the development and piloting of a Multi-Channel ICT-based Model of enhancing University engagement with smallholder farming communities in Uganda, codenamed “SUFACE”. The acronym, SUFACE was derived from the project Strengthening University Farming Communication Engagement which funded the work. Four main stages were followed in developing the model: (i) establishing requirements for developing an appropriate model and designing the model, (ii) developing the ICT platform to anchor the model, (iii) establishing knowledge and information centers (KICs), and (iv) training managers of KIC, extension workers and farmers. The model provides services in capturing farmer information needs, storage and indexing, data visualization, data search, information sharing, security and privacy. Preliminary indications are that the model has increased access to information and has fostered closer working relations between the university and farmers. Where the ICT infrastructure exists, this appears to be a financially viable approach for better linking universities with small farmers either directly or through local knowledge centres, NGOs or extension agencies. Key emerging issues include the need to develop local capacity for farmer query translation and exploring opportunities for automatic query translation and response.
title: International Law at Sea, Economic Warfare, and Britain's Response to the German U-boat Campaign during the First World War
Creators: name: Russell, Bruce
Publisher: name: The Open University
Year: 2008

description: This thesis examines, in three parts, the British naval blockade of Germany during the First World War. In the first part, it analyses the development of international law in the years leading up to the war and uncovers British planning for a campaign of economic warfare against Germany. In the second part, there is an investigation into Germany's use of unrestricted U-boat warfare as a response to the British blockade of Germany. There is also a review of the effect of the wartime blockades on both Britain and Germany. The final part of the thesis studies issues of international law by separating the rules and regulations from the humanitarian aspects; it concludes by reviewing the changing role of the United States throughout the war and the state of law in the immediate post-war era. Challenging existing literature, the conclusions of the research have been enhanced through the employment of both case studies and counterfactual history. The conclusions challenge Bobbitt's ideas on an epochal war and show that Britain adapted well to the rigours of the German U-boat campaign, although the changing role of the United States made a vital contribution to the war. This method of warfare both revolutionised the method of employment for submarines, but also doomed Germany to failure. The First World War at sea demonstrated that international law was unable to cope with the use of the U-boat. This thesis makes an original contribution to the body of academic literature on the First World War by investigating new areas of research and improving academic understanding of the emergent role played by international law.

description: Information from Universities is important for social transformation in Africa but the ‘Ivory Tower’ university status often constrains effective information sharing with farmers. To address this effective communication for regular flows of information in all directions along agricultural value chains must be established. This research was part of a community action research project to promote university-farmer engagement with a focus on the dissemination channels preferred and the usefulness of the information shared to the farmers. Data were collected using semi-structured questionnaires and focus group discussions with 184 farmers. Findings revealed that inter-personal communication approaches were strongly preferred by farmers and they were most particularly interested in receiving information on pest control, post-harvest technology, value addition and marketing. As information channels, radios were significantly preferred while mobile phones were surprisingly less preferred, despite the relatively widespread ownership. The farmers also found the information disseminated to be useful and relevant if delivered in a timely manner. To sustain the relationship beyond the project, a system that provides some interpersonal connection from a distance is required. Subsequent research is focused on an ICT system that provides a platform for long-term engagement between the university and farmers.

description: Technological innovations have driven economic development and improvement in living conditions throughout history. However, the majority of smallholder farmers in sub-Saharan Africa have seldom adopted or used science-based technological innovations. Consequently, several scholars have been persistently questioning the effectiveness of intervention models in smallholder agriculture. Following the agricultural innovation systems framework (AIS), this paper reviews a participatory framework known as the ‘Follow the Innovation’ (FTI) approach, which was developed in the research project ‘Economic and Ecological Restructuring of Land and Water Use in Khorezm’ (2001 - 2012) and employed in an ongoing BiomassWeb project ‘Improving food security in Africa through increased system productivity of biomass-based value webs’ (2013 - 2018). The review shows a need for a broader definition of innovation as an outcome of collaborative or collegiate participation of multi-stakeholders processes requiring scientists, extensionists, local communities and other stakeholders to perform five key tasks jointly. Salient implications of this review are highlighted for transdisciplinary research (such as in the BiomassWeb project) aiming at agricultural innovation development in complex environments.

description: We present K-band commissioning observations of the Mira star prototype o Cet obtained at the ESO Very Large Telescope Interferometer (VLTI) with the VINCI instrument and two siderostats. The observations were carried out between 2001 October and December, in 2002 January and December, and in 2003 January. Rosseland angular radii are derived from the measured visibilities by fitting theoretical visibility functions obtained from center-to-limb intensity variations (CLVs) of Mira star models (Bessel et al. 1996, Hofmann et al. 1998, Tej et al. 2003). Using the derived Rosseland angular radii and the SEDs reconstructed from available photometric and spectrophotometric data, we find effective temperatures ranging from T_eff=3192 +/- 200 K at phase phi=0.13 to 2918 +/- 183 K at phi=0.26. Comparison of these Rosseland radii, effective temperatures, and the shape of the observed visibility functions with model predictions suggests that o Cet is a fundamental mode pulsator. Furthermore, we investigated the variation of visibility function and diameter with phase. The Rosseland angular diameter of o Cet increased from 28.9 +/- 0.3 mas (corresponding to a Rosseland radius of 332 +/- 38 R_sun for a distance of D=107 +/- 12 pc) at phi=0.13 to 34.9 +/- 0.4 mas (402 +/- 46 R_sun) at phi=0.4. The error of the Rosseland linear radius almost entirely results from the error of the parallax, since the error of the angular diameter is only approximately 1 %.
