VLA Subaru/XMM-Newton Deep Field 1.4-GHz Source Catalog

This table contains results from the deep radio imaging at 1.4 GHz of the 1.3-deg&lt;sup&gt;2&lt;/sup&gt; Subaru/XMM-Newton Deep Field (SXDF), made with the Very Large Array (VLA) in B and C configurations. This resulted in a radio map of the entire field, and a catalog of 505 sources covering 0.8 deg&lt;sup&gt;2&lt;/sup&gt; to a peak flux density limit of 100 microJansky (&micro;Jy), which corresponds to signal-to-noise (S/N) ratios of between 5 and 8. Robust optical identifications are provided for 90 per cent of the sources, and suggested identifications are presented for all but 14 (of which seven are optically blank, and seven are close to bright contaminating objects). The authors show that the optical properties of the radio sources do not change with flux density, suggesting that active galactic nuclei (AGN) continue to contribute significantly at faint flux densities. they test this assertion by cross-correlating their radio catalog with the X-ray source catalog and conclude that radio-quiet AGN become a significant population at flux densities below 300 uJy, and may dominate the population responsible for the flattening of the radio source counts if a significant fraction of them are Compton-thick. The SXDF was observed with NRAO&#39;s VLA in B-array using the 14 overlapping pointings arranged an an hexagonal pattern that are listed in Table 1 of the reference paper. Three test observations of pointings 1, 4 and 6 were taken on 2001 May 17, and the rest of the data were obtained in 13 runs, each lasting 4.5 hours, between 2002 August 10 and September 9. All 14 pointings were re-observed in C-array on 2003 January 15 to provide additional information on larger angular scales. This table contains the catalog of 505 detected radio sources and their proposed optical counterparts (the latter taken mostly from the ultra-deep BR&iacute;z&#39; Suprime-Cam images of the SXDF). As mentioned above, 14 of these 505 radio sources have no suggested identifications. Additionally, 7 of the radio sources (source numbers 16, 114, 129, 263, 360, 361 and 488) have 2 listed optical identifications: in such cases, there are 2 entries for each source listed detailing the alternative optical counterparts, and with identical sets of radio parameters. Thus, there are 512 = 505 + 7 entries in this table. This table was created by the HEASARC in August 2013 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/372/741"&gt;CDS Catalog J/MNRAS/372/741&lt;/a&gt; file table3.dat.

ROSAT All-Sky Survey/ASIAGO-ESO QSO Survey Catalog

This table contains some of the first results of a survey for bright quasars (V &lt; 14.5 and R &lt; 15.4) covering the northern hemisphere at Galactic latitudes |b| &gt; 30 degrees. The photometric database is derived from the Guide Star and USNO catalogs. Quasars are identified on the basis of their X-ray emission measured in the ROSAT All-Sky Survey (RASS). The surface density of quasars brighter than 15.5 magnitudes turns out to be (10 +/- 2) x 10&lt;sup&gt;-3&lt;/sup&gt; degrees&lt;sup&gt;-2&lt;/sup&gt;, about 3 times higher than that estimated by the Palomar-Green (PG) survey. In the paper, the quasar optical luminosity function (LF) at 0.04 &lt; z &lt;= 0.3 is computed and shown to be consistent with a luminosity-dependent luminosity evolution of the type derived by La Franca &amp; Cristiani (1997AJ....113.1517L) in the range 0.3 &lt; z &lt;=2.2. The predictions of semianalytical models of hierarchical structure formation agree remarkably well with the present observations. This table was created by the HEASARC in September 2010 based on the combination of the electronic versions of Tables 2, 3, and 4 from the reference paper which were obtained from the CDS (their catalog J/AJ/119/2540).

Dynamical Masses of Selected Orbital Binary Systems

Orbital binary stars are essential objects for determining dynamical and physical properties of stars through a combined analysis of photometric and astrometric data. The authors have compiled a set of orbital binaries with known trigonometric parallaxes and orbits of high quality, using data from current versions of the Observatorio Astronomico Ramon Maria Aller Catalog (OARMAC) of Orbits and Ephemerides of Visual Double Stars (Docobo et al. 2001, AcA, 51, 353) and the Sixth Catalog of Orbits of Visual Binary Stars (ORB6: Mason and Hartkopf 2007, IAUS 240, 575; Hartkopf et al. 2001, AJ, 122, 3472), as well as including updated information from the Washington Double Star (WDS) Catalog and SIMBAD. They constructed distributions of orbital binaries of the dynamical mass, period, semi-major axis, and eccentricity of systems, which characterize the set. Some problems related to the parametrization of orbital binaries are also discussed in the paper. To compile the orbit list, the authors combined data from both OARMAC and ORB6. At this stage, they maintained systems without parallaxes, but removed systems without a period or semi-major axis. The resulting list contained 3139 orbits for 2278 pairs: 1588 pairs have a single orbit, 548 pairs have two orbits, 120 pairs have three orbits, 19 pairs have four orbits, one pair has five orbits, and two pairs have seven orbits. Table 1 in the reference paper (not part of this HEASARC table) contains a compiled set of 3139 orbit solutions for visual binary stars. Separate entries are provided for different pairs in multiple systems. Several solutions per pair are possible. Each entry includes main orbital elements (Semi-major axis, period, eccentricity with corresponding uncertainties), indication of multiplicity and number of solutions, as well as visual magnitudes, spectral classes of the components, parallax and interstellar extinction estimate. Table 2 in the reference paper (on which this HEASARC table is based) contains a refined set of 652 solely binary systems with reliable orbits and determined parallaxes. One entry in this table corresponds to one system. Three mass estimates are provided: (1) The dynamical mass with its uncertainty derived from Kepler&#39;s third law and its trigonometric parallax, (2) a photometric mass estimated from the visual magnitudes, parallax and mass-luminosity relation, and (3) a spectroscopic mass based on the mass-spectrum relation introduced by Straizys and Kuriliene (1981, Ap&amp;SS, 80, 353). Also provided for each system are the main orbital elements, the parallax, and the component magnitudes and spectral types. This table was created by the HEASARC in October 2014 based on the list of orbital binaries given in &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/546/A69"&gt;CDS Catalog J/A+A/546/A69&lt;/a&gt; file table2.dat.

Exoplanet Orbit Database

The Exoplanet Orbit Database is a database of well-determined orbital parameters of exoplanets, and their host stars&#39; properties. This database comprises spectroscopic orbital elements measured for planets orbiting their host stars from radial velocity and transit measurements as reported in the literature. The authors have also compiled fundamental transit parameters, stellar parameters, and the method used for the planets discovery. This Exoplanet Orbit Database includes all planets with robust, well measured orbital parameters reported in peer-reviewed articles. In addition to this HEASARC representation, the database is available in a searchable, filterable, and sortable form online through the Exoplanets Data Explorer table at &lt;a href="http://exoplanets.org"&gt;http://exoplanets.org&lt;/a&gt;, and the data can be plotted and explored through the Exoplanet Data Explorer plotter which is available at that web site. In their paper, the authors use the Data Explorer to generate publication-ready plots, giving three examples of the signatures of exoplanet migration and dynamical evolution: They illustrate the character of the apparent correlation between mass and period in exoplanet orbits, the different selection biases between radial velocity and transit surveys, and that the multi-planet systems show a distinct semi-major-axis distribution from apparently singleton systems. This table was first created by the HEASARC in August 2012 based on a machine-readable version of the Exoplanet Orbit Database which was obtained from the authors&#39; web site (&lt;a href="http://exoplanets.org"&gt;http://exoplanets.org&lt;/a&gt;), file exoplanets.csv.

GOODS-S IRS 16 micron Catalog

The Great Observatories Origins Deep Survey (GOODS) aims to unite extremely deep observations from NASA's Great Observatories (Spitzer, Hubble and Chandra), ESA's Herschel and XMM-Newton, and the most powerful ground-based facilities. The aim is to survey the distant universe to the faintest flux limits across the broadest range of wavelengths.\n\nGOODS Spitzer IRS 16 micron observations surveyed 150 square arcminutes in each of the two GOODS fields (North and South), to an average 3 sigma depth of 40 and 65 microJy, respectively. These sources have been cross-correlated with Spitzer, Chandra, and HST measurements in other bands.

NormaArmRegionChandraSurveyPoint&ExtendedSourceCatalog

This table contains the catalog of 1,415 X-ray sources identified in the Norma Arm Region Chandra Survey (NARCS), which covers a 2 degree x 0.8 degree region in the direction of the Norma spiral arm to a depth of ~ 20 ks. Of these sources, 1,130 are point-like sources detected with &gt;= 3-sigma confidence in at least one of three energy bands (0.5 - 10, 0.5 - 2, and 2 - 10 keV), five have extended emission, and the remainder are detected at low significance. Since most sources have too few counts to permit individual classification, they are divided into five spectral groups defined by their quantile properties. The authors analyze stacked spectra of X-ray sources within each group, in conjunction with their fluxes, variability, and infrared counterparts, to identify the dominant populations in this survey. They find that ~ 50% of their sources are foreground sources located within 1 - 2 kpc, which is consistent with expectations from previous surveys. Approximately 20% of sources are likely located in the proximity of the Scutum-Crux and near Norma arm, while 30% are more distant, in the proximity of the far Norma arm or beyond. The authors argue that a mixture of magnetic and non-magnetic cataclysmic variables dominates the Scutum-Crux and near Norma arms, while intermediate polars and high-mass stars (isolated or in binaries) dominate the far Norma arm. In the paper, they also present the cumulative number count distribution for sources in this survey that are detected in the hard energy band. A population of very hard sources in the vicinity of the far Norma arm and active galactic nuclei dominate the hard X-ray emission down to f&lt;sub&gt;X&lt;/sub&gt; ~ 10&lt;sup&gt;-14&lt;/sup&gt; erg cm&lt;sup&gt;-2&lt;/sup&gt; s&lt;sup&gt;-1&lt;/sup&gt;, but the distribution curve flattens at fainter fluxes. The authors find good agreement between the observed distribution and predictions based on other surveys. Chandra ACIS-I observations were performed in faint mode of a 2 degree by 0.8 degree region of the Norma spiral arm in 2011 June. This field was subdivided into 27 pointings; Table 1 in the reference paper reports their coordinates and exposure times and Figure 1 (op. cit.) is a mosaic image of the survey. The observing strategy was to cover a wide area with relatively uniform flux sensitivity and good spatial resolution; therefore, the authors chose field centers spaced by 12 arcminutes, which provided roughly 70 arcminute&lt;sup&gt;2&lt;/sup&gt; of overlap on the outskirts of adjacent observations such that the additional exposure time in these overlapping regions partly made up for the worsening point-spread function (PSF) at large off-axis angles. This table was created by the HEASARC in March 2015 based on electronic versions of Tables 3, 4 and 5 from the reference paper which were obtained from the ApJ web site.

GLIMPSE II Archive

The Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSEII) imaged longitudes ±10◦ of the central region of the Galaxy. The latitude coverage is ±1◦ from |l| =10◦to 5◦, ±1.5◦ from |l| =5◦to 2◦, and ±2◦ from |l| =2◦to 0◦. GLIMPSEII coverage excludes the Galactic center region l=±1◦, b=±0.75◦ observed by the GALCEN GO program (PID=3677). GLIMPSEII had two-epoch coverage for a total of three visits on the sky. The observations consisted of two 1.2 second integrations at each position in the first epoch of data taking (September 2005) and a single 1.2 second integration at each position six months later (April 2006).\n\nThe GLIMPSEII Archive (GLMIIA or the “Archive”) consists of point sources with a signal- to-noise > 5 in at least one band and less stringent selection critera than the Catalog. The photometric uncertainty is typically < 0.3 mag. The GLIMPSEII Catalog is a subset of the Archive, but note that the entries for a particular source might not be the same due to additional nulling of magnitudes in the Catalog because of the more stringent requirements.

AfriSAR: Aboveground Biomass for Lope, Mabounie, Mondah, and Rabi Sites, Gabon

This dataset provides gridded estimates of aboveground biomass (AGB) for four sites in Gabon at 0.25 ha (50 m) resolution derived with field measurements and airborne LiDAR data collected from 2010 to 2016. The sites represent a mix of forested, savannah, and some agricultural and disturbed landcover types: Lope site, within Lope National Park; Mabounie, mostly forested site; Mondah Forest, protected area; and the Rabi forest site, part of the Smithsonian Institution of Global Earth Observatories world-wide network of forest plots. Plot-level biophysical measurements of tree diameter and tree height (or estimated by allometry) were performed at 1 ha and 0.25 ha scales on multiple plots at each site and used to derive AGB for each tree and then summed for each plot. Aerial LiDAR scans were used to construct digital elevation models (DEM) and digital surface models (DSM), and then the DEM and DSM were used to construct a canopy height model (CHM) at 1 m resolution. After checking site-plot locations against the CHM, mean canopy height (MCH) was computed over each 0.25 ha. A single regression model relating MCH and AGB estimates, incorporating local height based on the trunk DBH (HD) relationships, was produced for all sites and combined with the CHM layer to construct biomass maps at 0.25 ha resolution.

M 31 Disk Chandra PHAT Survey: X-Ray Source Catalog

The X-ray source populations within galaxies are typically difficult to identify and classify with X-ray data alone. The authors break through this barrier by combining deep new Chandra ACIS-I observations with extensive Hubble Space Telescope (HST) imaging from the Panchromatic Hubble Andromeda Treasury (PHAT) of the M 31 disk. They detect 373 X-ray sources down to 0.35-8.0keV flux of 10&lt;sup&gt;-15&lt;/sup&gt;erg/cm&lt;sup&gt;-2&lt;/sup&gt;/s over 0.4deg&lt;sup&gt;2&lt;/sup&gt;, 170 of which are reported for the first time. The authors identify optical counterpart candidates for 188 of the 373 sources, after using the HST data to correct the absolute astrometry of our Chandra imaging to 0.1&quot;. While 58 of these 188 are associated with point sources potentially in M 31, over half (107) of the counterpart candidates are extended background galaxies, 5 are star clusters, 12 are foreground stars, and 6 are supernova remnants. Sources with no clear counterpart candidate are most likely to be undetected background galaxies and low-mass X-ray binaries in M 31. The hardest sources in the 1-8keV band tend to be matched to background galaxies. The 58 point sources that are not consistent with foreground stars are bright enough that they could be high-mass stars in M 31; however, all but 8 have optical colors inconsistent with single stars, suggesting that many could be background galaxies or binary counterparts. For point-like counterparts, the authors examine the star formation history of the surrounding stellar populations to look for a young component that could be associated with a high-mass X-ray binary. The associated star formation histories for sources in the catalog are available in the linked table &lt;a href="/W3Browse/chandra/m31phatsfh.html"&gt;M31PHATSFH&lt;/a&gt;. In 2015 October, the authors observed the Panchromatic Hubble Andromeda Treasury (PHAT) footprint with Chandra with 7 pointings. The footprints are overlaid on a GALEX NUV image of M 31, along with the corresponding HST coverage, in Figure 1 of the reference paper. At each pointing they observed for about 50ks in VF mode (Chandra ObsID 17008 to 17014 spanning 2015 Oct 06 to 2015 Oct 26). This table was created by the HEASARC in April 2020 based upon the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/239/13"&gt;CDS Catalog J/ApJS/239/13&lt;/a&gt; file table4.dat and table6.dat.

VG2 URA PWS RAW EXPERIMENT WAVEFORM                                      60MS V1.0

This data set consists ofelectric field waveform samples from the Voyager 2 Plasma WaveReceiver waveform receiver obtained during the Uranus encounter.The waveforms are collections of 4-bit samples of the electricfield measured by the dipole electric antenna at a rate of 28,800samples per second.  1600 samples are collected in 55.56 msecfollowed by a 4.44-msec gap. Each 60-msec interval constitutes aline of waveform samples. The data set includes about 271 frames ofwaveform samples consisting of up to 800 lines, each.  Thetelemetry format for the waveform data is identical to that forimages, hence the use of line and frame as constructs in describingthe form of the data.  The waveform is sampled through a bandpassfilter with a passband of 40 Hz to 12 kHz.  The 4-bit samplesprovide sixteen digital values of the electric field with alinear amplitude scale, but the amplitude scale is arbitrarybecause of the automatic gain control used in the waveformreceiver.  The instantaneous dynamic range afforded by the 4bit samples is about 23 db, but the automatic gain control allowsthe dominant signal in the passband to be set at the optimumlevel to fit within the instantaneous dynamic range.  With the gaincontrol, the overall dynamic range of the waveform receiveris about 100 db.
