title: ASKAP Data Products for Project AS108 (ASKAP Pilot Survey for GASKAP-HI): catalogues

description: These observations will form part of the ASKAP pilot survey program. This is a joint exercise between CASS and the ASKAP Survey Science Teams to conduct a series of observations to learn how to conduct large-scale surveys using the full capabilities of this new telescope. The key goal of the pilot survey program is to establish readiness for full survey operations, including determining and testing observing and processing strategies, and data validation and release. The observations collected here are primarily for GASKAP-HI.

title: Australia Telescope Compact Array Data Products for Project C1967 (The ATLAS 1.4 GHz survey): derived catalogues DR1

description: ATLAS is a project to image seven square degrees of sky, in two fields (CDF-S and ELAIS-S1), at radio wavelengths, to an rms of about 15 µJy, making it the widest deep radio survey aver attempted. The fields are chosen to cover the Spitzer Wide-Area IR Extragalactic Survey (SWIRE), and the radio images cut through the dust, to trace the cosmic history of AGN and star-forming galaxies.

Data release 1 contains two catalogues from the deep ATLAS radio observations of the CDFS-SWIRE field:

1) radio components; and 
2) radio sources with their identifications and classifications

title: Southern Galactic Plane Survey (SGPS) - HI Observations

description: The Southern Galactic Plane Survey (SGPS) was a large-scale project to image at arcminute resolution the H I spectral line and 21 cm continuum emission in parts of the plane of the Milky Way. The survey covered Galactic longitudes 253 deg &lt;= l &lt;= 358 deg and latitudes |b|&lt;=1.5d (SGPS I), plus a first quadrant extension covering 5deg&lt;=l&lt;=20deg and |b|&lt;=1.5d (SGPS II). The survey combines data from the Australia Telescope Compact Array and the Parkes Radio Telescope for sensitivity to angular scales ranging from 2' to several degrees. The combined data cover 325 deg2 and have an rms sensitivity of 1.6 K. This data set provides an unprecedented view of the neutral component of interstellar hydrogen in the inner Milky Way.

title: ASKAP Data Products for Project AS034 (ASKAP Early Science Broadband Survey): derived images

description: These data are a combined mosaic of two overlapping ASKAP tiles covering the GAMA-23 field.

The following is copied from the validation notes of the source SBIDs and also apply to these data.

These data represent a test observation with the full ASKAP array. While it may be useful for science purposes the primary goal of the release is to seek feedback on data quality from the science community. Although the image approaches expected noise levels in most areas, a common feature of early ASKAP data has been some low-level artefacts (at ~1%) very close to bright sources (a few hundred mJy and above). These artefacts generally appear as radial stripes and rapidly fade away from the source. The origin of these artefacts is yet to be determined, but they do not seem to emulate any known instrumental effect taken into account in commonly used wideband/widefield calibration and imaging software packages (such as ASKAPsoft, casa etc.). The spectral indices given in the catalogues were derived from Taylor-term imaging, which is a technique not yet widely used in radio astronomy. It has been identified that the distribution of the spectral indices in these catalogues deviates significantly from expectations for reasons that are not yet understood. Fitting spectra to sources in the continuum cubes is recommended to attain more reliable spectral indices. While the commissioning team investigates the cause of these issues in detail, we do not wish to hold the release of otherwise good quality data. Hence these test observations are being released, but with the validation flag set to “uncertain” — meaning user discretion is necessary in the interpretation for science purposes. Users should perform their own analysis of the flux scale, source positions and spectral indices given. The ASKAP operations team would be glad to receive feedback on any issues discovered.

title: ASKAP Project AS108 GASKAP-HI Pilot Survey: SMC HI Emission Cube

description: This collection contains a 3901x3471x220 pixel data cube consisting of ASKAP data of the neutral hydrogen (HI) emission in the SMC feathered with regridded Parkes data. This cube covers a LSRK velocity range of 40.0 km/s to 253.9 km/s at a spectral resolution of 0.98 km/s. The rms noise level in a single spectral channel is 1.1 K at an angular resolution of 30’’ with an individual pixel size of 7''. This rms level translates to a 5-sigma HI column density detection limit of 4.4e19 cm^-2 over a 20 km/s line width. These data were produced with a custom imaging pipeline that utilizes the joint deconvolution capabilities of WSClean, a third party software suite designed specifically for wide-field imaging, to ensure emission that extends across the boundaries of the ASKAP primary beams is accurately recovered. A multi-scale CLEAN algorithm was employed with scales ranging from 0, 4, 8, 16, 32, 64, 128, and 256 pixels. Other data products include a map of the primary beam response across the ASKAP field-of-view and an integrated intensity image computed over the velocity range of 235.4 km/s to 60.5 km/s. Please see PAPER PLACEHOLDER for comprehensive details on the calibration, imaging, and properties of these data.

title: Primary production and environmental variables from 1971 to 2021 in the North Basin of Lake Biwa

description: Abstract: Global climate change and anthropogenic oligotrophication are expected to reshape the dynamics of primary production (PP) in aquatic ecosystems however, few studies have explored their long-term effects. In theory, the PP of phytoplankton in Lake Biwa may decline over decades due to warming, heightened stratification, and anthropogenic oligotrophication. Furthermore, the PP of large phytoplankton, which are inedible to zooplankton, along with biomass-specific productivity (PBc), could decrease. In this study, data from 1976–2021 and active fluorometry measurements taken in 2020 and 2021 were evaluated. Quantitatively, the temporal dynamics of mean seasonal PP during 1971–2021 were assessed according to the carbon fixation rate to investigate relationships among environmental factors. Qualitatively, phytoplankton biomass, PP, and PBc were measured in two size fractions [edible (S) or inedible (L) for zooplankton] in 2020 and 2021, and the L:S balance for these three measures was compared between 1992 (low-temperature/high-nutrient conditions) and 2020–2021 (high-temperature/low-nutrient conditions) to assess seasonal dynamics. The results indicated that climate change and anthropogenic oligotrophication over the past 50 years have diminished Lake Biwa's PP since the 1990s, impacting the phenology of PP dynamics. However, the L:S balance in PP and PBc has exhibited minimal change since 1992. These findings suggest that, although climate change and oligotrophication may reduce overall PP, they do not markedly alter the inedible/edible phytoplankton balance in terms of PP and PBc. Instead, as total PP declines, the production of small edible phytoplankton decreases proportionally, potentially affecting trophic transfer efficiency and material cycling in Lake Biwa.
