Australia Telescope 20-GHz (AT20G) Survey Catalog

The Australia Telescope 20-GHz Survey (AT20G) is a blind radio survey carried out at 20 GHz with the Australia Telescope Compact Array (ATCA) from 2004 to 2008, and covers the whole sky south of declination 0 degrees. The AT20G source catalogue presented here is an order of magnitude larger than any previous catalogue of high-frequency radio sources, and includes 5890 sources above a 20-GHz flux-density limit of 40 mJy. All AT20G sources have total intensity and polarisation measured at 20 GHz, and most sources south of declination -15 degrees also have near-simultaneous flux-density measurements at 5 and 8 GHz. A total of 1559 sources were detected in polarised total intensity at one or more of the three frequencies. The completeness of the AT20G source catalog is 91% above 100 mJy/beam and 79% above 50 mJy/beam in regions south of Declination -15 degrees. North of -15 degrees, some observations of sources between 14 and 20 hours in RA were lost due to bad weather and could not be repeated, so the catalog completeness is lower in this region. Each detected source was visually inspected as part of the authors&#39; quality control processs, and so the reliability of the final catalog is essentially 100%. This table was created by the HEASARC in March 2010 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/402/2403/"&gt;CDS Catalog J/MNRAS/402/2403/&lt;/a&gt; file at20gcat.dat.

GIOTTO DUST IMPACT DETECTOR SYSTEM DATA V1.0

Dust Impact Detection System (DIDSY) consists of six independent subsystems with the primary aim of registering the impacts of all particulates of significant mass incident on the probe during the post-perihelion encounter with Comet Halley in 1986. Mounted on Giotto's front dust shield, the detectors will determine the mass spectrum of the dust, with a limiting sensitivity of some 10^^-17^^ g, increasing to the largest grain masses encountered along Giotto's trajectory through the cometary environment with an ultimate spatial resolution of some 70 km. An additional detector is located on the rear shield to monitor those dust particles (m > ~ 5 X 10^^-7^^ g) that are able to penetrate the front dust shield. An ambient plasma monitor is also incorporated into DIDSY to measure the inJpact plasma generated by both dust and gas impacts on the spacecraft. The system is controlled and its data processed by a microprocessor-based system that allows the wide range of anticipated impact rates (varying from a few per minute, to ~ 10^6 s^^-1^^ at closest approach) to be handled. The instrument weighs 2.26 kg and consumes 1.9 W of power during normal operation.

AMSR2/GCOM-W1 downscaled surface soil moisture (LPRM) L2B V001 (LPRM_AMSR2_DS_SOILM2) at GES DISC

AMSR2/GCOM-W1 downscaled surface soil moisture (LPRM) L2B V001 is a Level 2 (swath) data set. Its land surface parameters, surface soil moisture, land surface (skin) temperature, and vegetation water content, are derived from passive microwave remote sensing data from the Advanced Microwave Scanning Radiometer 2 (AMSR2), using the Land Parameter Retrieval Model (LPRM). Each swath is packaged with associated geolocation fields. The data set covers the period from May 2012, when the Japan Aerospace Exploration Agency (JAXA) Global Change Observation Mission-1st Water GCOM-W1 satellite was launched, to the present. The spatial resolution of the data is based on a resampling of the nominally 46 and 31 km resolutions, respectively, of AMSR2's C and X bands (6.9/7.3 and 10.7 GHz, respectively) to 25 km by 25 km and then a downscaling, using the smoothing filter-based intensity modulation (SFIM) technique, to 10 km by 10 km grids. The LPRM is based on a forward radiative transfer model to retrieve surface soil moisture and vegetation optical depth. The land surface temperature is derived separately from the AMSR2's Ka-band (36.5 GHz). A unique feature of this method is that it can be applied at any microwave frequency, making it very suitable to exploit all the available passive microwave data from various satellites. Input data are from the AMSR2 spatial-resolution-matched brightness temperatures (L1SGRTBR) product, archived at JAXA.

Hungry Giants: WISE Excesses and Lithium Study

We have assembled a set of 316 targets thought to be K giants, two thirds of which are thought to be Li-rich, in order to test the association between IR excesses and lithium abundances. The targets come from the dlR97 study (biased toward IR-bright sources), the C12 study (assembled with limited biases to test correlations of various stellar parameters), and a wide variety of literature identifying Li-rich K giants. For these targets, we assembled a multiwavelength catalog spanning optical through 100 um data, using SDSS, NOMAD, 2MASS, DENIS, WISE, IRAS, AKARI, MSX, and Spitzer data.

ROSAT All-Sky Survey Candidate Isolated Neutron Stars

Using new and archival observations made with the Swift satellite and other facilities, the authors examine 147 X-ray sources selected from the ROSAT All-Sky-Survey Bright Source Catalog (RASS/BSC) to produce a new limit on the number of isolated neutron stars (INSs) in the RASS/BSC, the most constraining such limit to date. Independent of X-ray spectrum and variability, the number of INSs is &lt;= 48 (90% confidence). Restricting attention to soft (kT&lt;sub&gt;eff&lt;/sub&gt; &lt; 200 eV), non-variable X-ray sources - as in a previous study - yields an all-sky limit of &lt;= 31 INSs. In the course of their analysis, the authors identify 5 new high-quality INS candidates for targeted follow-up observations. A future all-sky X-ray survey with eROSITA, or another mission with similar capabilities, can be expected to increase the detected population of X-ray-discovered INSs from the 8 - 50 in the BSC, to (for a disk population) 240 - 1500, which will enable a more detailed study of neutron star population models. Following selection of the INS candidates, short (~ 1 ks) follow-up observations with Swift/XRT were obtained for 92 of the candidates; these observations decreased the X-ray positional uncertainty (the systematic positional error associated with Swift blind pointing observations is on the order of 3.5&quot;). The authors obtained (where possible) contemporaneous UV observations with Swift/UVOT for counterpart identification with off-band objects. This table was created by the HEASARC in May 2012 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/714/1424"&gt;CDS Catalog J/ApJ/714/1424&lt;/a&gt; files table1.dat and table2.dat.

2MASS 6X Merged Extended Source Information Table

During the final months of 2MASS observatory operations, a campaign of targeted "long exposure" observations was carried out during times when no previously unscanned parts of the sky were available for the main survey. These observations used the same freeze-frame scanning technique employed for the survey, but with READ2-READ1 exposures six times longer than was used for normal survey observations (hence they are referred to as "6x" observations). The 2MASS 6x measurements were intended to probe ~1 magnitude deeper than the main survey in unconfused regions.\n\nApproximately 590 deg2 of sky distributed in 30 targeted regions were scanned at least once using the long exposures. Most of this area is concentrated in two large, comprehensive surveys of the Large and Small Magellanic Clouds, 383 deg2 and 127 deg2, respectively. Twenty-eight additional smaller fields were mapped in the 6x mode from both observatories, covering targets that include the Pleiades open cluster, galactic star formation complexes, M31, nearby galaxy clusters and the Lockman Hole. \n\nThe merged source tables contain the mean positions magnitudes and uncertainties for sources detected multiple times in each of the 2MASS data sets. The merging was carried out using an autocorrelation of the respective databases to identify groups of extractions that are positionally associated with each other, all lying within a 1.5" radius circular region. A number of confirmation statistics are also provided in the tables that can be used to test for source motion and/or variability, and the general quality of the merge.

Swift Gamma Ray Burst Compilation by Burst Advocate

This database table includes the early results published in the Gamma-Ray Burst Coordinates Network (GCN) circulars on GRBs detected by the Swift observatory and GRBs detected first by other observatories and followed by Swift. The Swift observatory has a rapid (minute timescale) response to GRB detection and performs sensitive X-ray and optical afterglow observations of hundreds of GRBs on all timescales, from minutes to even months later. The instrumentation consists in a large field of view (FOV) instrument, the Burst Alert Telescope (BAT, 15-150 keV) and two narrow field of view instruments, the Ultraviolet/Optical Telescope (UVOT) and the X-ray Telescope (XRT). The BAT searches the sky for gamma-ray bursts (GRBs), determines their location with a precision of a few arcminutes, and triggers an autonomous spacecraft slew to place the burst in the FOV of the narrow field instruments. The first-look data from the three Swift instruments for a newly discovered GRB and its afterglow are transmitted to the ground via TDRSS. The complete telemetry (including the messages transmitted via TDRSS) is subsequently sent down via the Malindi ground station. The information transmitted via TDRSS are broadcast via the the Gamma-Ray Burst Coordinates Network (GCN) followed by subsequent GCN circular based on the early ground analysis of the data collected by Malindi. If the GRB is triggered by Swift , this table records the initial characteristic associated to a burst obtained with the data coming via TDRSS and initial data downloaded via Malindi which results are published via the GCN. In addition the table reports other burst characteristics as for redshift obtained by observations with ground observatories. If the GRB is detected first by other observatories, the table reports results obtained with the ground analysis of the Malindi data and published via the GCN. This database table is generated by compiling the results of the GCN circulars. It was added to the HEASARC database in March 2025. During operation, it is updated weekly and/or for any new trigger. This table is also available at &lt;a href="https://swift.gsfc.nasa.gov/archive/grb_table/"&gt;https://swift.gsfc.nasa.gov/archive/grb_table/&lt;/a&gt;. This is a service provided by NASA HEASARC .

Hipparcos Input Catalog

This database table contains the Hipparcos Input Main Cataloge of 118209 stars. The Hipparcos Input Catalogue was constructed as the observing program for the European Space Agency&#39;s Hipparcos astrometry mission. The requirements of the project in terms of completeness, sky coverage, astrometric and photometric accuracy, as well as the necessary optimization of the scientific impact, resulted in an extended effort to compile and homogenize existing data, to clarify sources and identifications, and, where needed, to collect new data matching the required accuracy. This has resulted in an unprecedented catalog of stellar data including up-to-date information of positions, proper motions, magnitudes and colors, and (wherever available) spectral types, radial velocities, multiplicity and variability information. The catalog is complete to well-defined magnitude limits and includes a substantial sampling of the most important stellar categories present in the solar neighborhood beyond these limits. The magnitudes vary from 7.3 to 9 mag as a function of galactic latitude and spectral type, and there are no stars fainter than about V=13 mag. The 118209 stars of the Hipparcos Input Catalogue were selected from some 214000 distinct candidates contained in some 214 observations programs. This is a service provided by NASA HEASARC .

RCW 38 Chandra X-Ray Point Source Catalog

This table contains the results of a 96.7-ks Chandra observation of one of the youngest, most embedded, and most massive young stellar clusters studied to this date in X-rays, namely the embedded young cluster, RCW 38. 460 X-ray sources were detected in the field, of which 360 are confirmed to be associated with the RCW 38 cluster. The cluster members range in luminosity from 10&lt;sup&gt;30&lt;/sup&gt; to 10&lt;sup&gt;33.5&lt;/sup&gt; erg/s. Over 10% of the cluster members with over 100 counts were found to exhibit flares, while about 15% of the cluster members with over 30 counts were variable. Of the sources identified as cluster members, 160 have near-infrared (NIR) counterparts either in the Two Micron All Sky Survey (2MASS) database or which were detected via Very Large Telescope observations. Of these, about 20% appear to have optically thick disks. An additional 353 cluster members were identified through NIR observations, of which at least 50% possess optically thick disks. Over 100 X-ray sources were fit as absorbed Raymond-Smith-type plasmas and the authors found that the column to the cluster members varies from 10&lt;sup&gt;21.5&lt;/sup&gt; to 10&lt;sup&gt;23&lt;/sup&gt; cm&lt;sup&gt;-2&lt;/sup&gt;. Comparing the gas to dust absorption signatures in these stars they found N&lt;sub&gt;H&lt;/sub&gt; = A&lt;sub&gt;V&lt;/sub&gt; (2 x 10&lt;sup&gt;21&lt;/sup&gt;) cm&lt;sup&gt;-2&lt;/sup&gt;. They also found that the cluster contains 31 candidate OB stars and is centered about 10&quot; (0.1 pc) west of the primary source of its ionization, the O5 star IRS 2. The cluster has a peak central density of about 400 X-ray sources pc&lt;sup&gt;-2&lt;/sup&gt;. The authors estimate that the total cluster membership exceeds 2000 stars. The Chandra observation of RCW 38 took place on 2001 December 10-11 and lasted 96.7 ks. It used Advanced CCD Imaging Spectrometer (ACIS) chips 0, 1, 2, 3, 6 and 7 in very faint mode. The combined field of view (FOV) of the 4 chips in the imaging array (0-3, ACIS-I) is 16.9&#39; x 16.9&#39;. The aimpoint of the array was 8 59 19.20, -47 30 22.0 (J2000.0), and Chandra&#39;s roll angle was 51 degrees. The source detection algorithm PWDetect was run on the cleaned events list across the entire ACIS-I array, and found 460 sources, including 31 sources with more than 200 net counts, 49 sources with 100-200 net counts, 71 sources with 50-100 net counts, and 78 sources with 20-50 net counts. NIR matches were found for 349 of the 460 X-ray sources, including 294 of the 360 cluster members and 55 of the 100 nonmembers. This table was created by the HEASARC in February 2007 based on the merger of Tables 1, 10 and 11 from the reference paper which were obtained from the AJ website. It does not include the results from either the quartile analysis of the sources which were presented in Tables 2 and 3 or of the spectral analysis of some of the sources which were presented in Tables 5 through 9 of the reference paper.

ICE ENERGETIC PARTICLE ANISOTROPY SPECTROMETER DATA V1.0

In this G-Z dataset, observations from channels E1 to E5 (table below) are included since cometary ions were not detected in the higher energy channels. For each of these channels, particle counts are accumulated in eight azimuthal sectors of 45 deg. width in each telescope. The sectors are numbered from 1 to 8 anticlockwise when viewed from above the ecliptic, with Sector 1 centered on the sun- Earth line, i.e. it views in the sunward direction and detects ions streaming away from the Sun. At Giacobini-Zinner, a complete 3- dimensional distribution function was obtained at 32 s intervals during the main encounter phase, changing to 64 s at greater distances e.g. after 1830 UT on 12 September outbound.
