Sydney University Molonglo Sky Survey (SUMSS) Source Catalog

The Sydney University Molonglo Sky Survey (SUMSS) is a radio imaging survey of the sky south of declination, delta = -30 degrees (a total area of 8100 square degrees) carried out with the Molonglo Observatory Synthesis Telescope (MOST) operating at 843 MHz. The survey consists of 629 4.3 degrees by 4.3 degrees mosaic images with a resolution of 45&quot; by 45&quot; x cosec delta, and a limiting peak brightness of 6 mJy/beam at declinations delta &lt;= 50 degrees, and 10 mJy/beam at delta &gt; 50 degrees. The SUMSS is therefore similar in sensitivity and resolution to the northern NRAO VLA Sky Survey (NVSS). This table based on the latest version of the SUMSS Source Catalog of radio sources (which uses all of the released mosaics). Sources were found by fitting two-dimensional Gaussians to SUMSS mosaics. Positions in the catalog are accurate to within 1-2&quot; for sources with peak brightness &gt;= 20 mJy/beam, and are always better than 10&quot;. The internal flux density scale is accurate to within 3%. Image artifacts were classified using a decision tree, which correctly identified and rejected spurious sources in over 96% of cases. Analysis of the catalog shows that it is highly uniform and is complete to 8 mJy at delta &lt;= -50 degrees, and to 18 mJy at delta &gt; -50 degrees. This HEASARC table was initially created in August 2005. It is updated automatically within a week of any detected change to the SUMSS Source Catalog as obtained from the SUMSS Website at the following URL: &lt;pre&gt; &lt;a href="https://web.archive.org/web/20241228020055/"&gt;https://web.archive.org/web/20241228020055/&lt;/a&gt;&lt;a href="http://www.astrop.physics.usyd.edu.au/sumsscat/update"&gt;http://www.astrop.physics.usyd.edu.au/sumsscat/update&lt;/a&gt; &lt;/pre&gt; This is a service provided by NASA HEASARC .

ROSAT North Ecliptic Pole Survey X-Ray Source Catalog

This table contains the ROSAT North Ecliptic Pole (NEP) Survey X-Ray Source Catalog. The sky around the NEP, at RA (J2000.0) = 18h00m00s, Declination (J2000.0) = +66d33&#39;39&quot;, has the deepest exposure of the entire ROSAT All-Sky Survey (RASS). The NEP is an undistinguished region of moderate Galactic latitude, b = 29.8 degrees, and hence it is suitable for compiling statistical samples of both Galactic and extragalactic objects. The authors have made such a compilation in the 80.6 square degrees region surrounding the NEP. Their sample fully exploits the properties of the RASS, since the only criteria for inclusion are source position and significance, and it yields the deepest large solid angle contiguous sample of X-ray sources to date. They find 442 unique sources above a flux limit ~2 x 10&lt;sup&gt;-14&lt;/sup&gt; ergs cm&lt;sup&gt;-2&lt;/sup&gt; s&lt;sup&gt;-1&lt;/sup&gt; in the 0.5-2.0 keV band. In this table, the X-ray properties of these sources as determined from the RASS are presented. These include positions, fluxes, spectral information in the form of hardness ratios, and angular sizes. This table was created by the HEASARC in February 2006 based on a machine-readable version of Table 4 in the above paper which was obtained from the electronic ApJ website.

EXOSAT ME Spectra and Lightcurves

The EXOSAT Medium Energy experiment (ME) was an array of eight proportional counters with a total geometric area of 1600 cm&lt;sup&gt;2&lt;/sup&gt;. The field of view was square and 0.75 degrees x 0.75 degrees FWHM on each side. Each proportional counter consisted of an argon chamber on top of a xenon chamber separated by a 1.5 mm beryllium window. The fractional energy resolution, dE/E, was 21(E/6 keV)&lt;sup&gt;-0.5&lt;/sup&gt; percent FWHM for the argon chambers. The output from each chamber was pulse height analyzed into 128 channels with the argon chambers sensitive from 1-20 keV and the xenon from 5-50 keV. To optimize the background subtraction, each half of the detector array was alternately offset to a source-free region of sky to monitor the particle background. Only results from the argon detectors are included in the EXOSAT ME database. The high count rates given by the ME required OBC (on board computer) programs to compress the data prior to their being telemetered. Depending on the objective of the observation the OBC programs traded time resolution against spectral information. Depending on the telemetry load, and the OBC programs running for the other two experiments, two or three ME programs could be run simultaneously. The spectral orientated programs gave spectra plus intensity profiles. The timing programs gave purely intensity profile data with in some cases selectable channels. The highest time resolution possible for a single selectable energy band was 0.2 ms. The products available within this database has been created using the data sampled by the spectral orientated OBC programs. This is a service provided by NASA HEASARC .

WISE/2MASS/RASS (W2R) AGN Sample Catalog

The authors of this catalog have developed the S&lt;sub&gt;IX&lt;/sub&gt; statistic to identify bright, highly likely active galactic nucleus (AGN) candidates solely on the basis of Wide-field Infrared Survey Explorer (WISE), Two-Micron All-Sky Survey (2MASS), and ROSAT All-Sky Survey (RASS) data. This statistic was optimized with data from the preliminary WISE survey and the Sloan Digital Sky Survey, and tested with Lick 3 m Kast spectroscopy. The authors find that sources with S&lt;sub&gt;IX&lt;/sub&gt; &lt; 0 have a &gt;~ 95% likelihood of being an AGN (defined in this paper as a Seyfert 1, quasar, or blazar). This statistic was then applied to the full WISE/2MASS/RASS dataset, including the final WISE data release, to yield the &quot;W2R&quot; sample of 4316 sources with S&lt;sub&gt;IX&lt;/sub&gt; &lt; 0. Only 2209 of these sources are currently in the Veron-Cetty and Veron (VCV) Catalog of spectroscopically confirmed AGNs, indicating that the W2R sample contains nearly 2000 new, relatively bright (J &lt;~ 16) AGNs. The authors utilize the W2R sample to quantify biases and incompleteness in the VCV Catalog. They find that it is highly complete for bright (J &lt; 14), northern AGNs, but the completeness drops below 50% for fainter, southern samples and for sources near the Galactic plane. This approach also led to the spectroscopic identification of 10 new AGNs in the Kepler field, more than doubling the number of AGNs being monitored by Kepler. The W2R sample contains better than 1 bright AGN every 10 deg&lt;sup&gt;2&lt;/sup&gt;, permitting construction of AGN samples in any sufficiently large region of sky. This table contains the 4316 sources comprising the W2R sample. This table was created by the HEASARC in June 2012 based on an electronic version of Table 3 from the reference paper which was obtained from the ApJ website.

LALA Cetus Field Chandra X-Ray Point Source Catalog

The 174 ks Chandra Advanced CCD Imaging Spectrometer (ACIS) exposure of the Large Area Lyman Alpha Survey (LALA) Cetus field is the second of the two deep Chandra images on LALA fields. In their paper, the authors present the Chandra X-ray sources detected in the Cetus field, along with an analysis of X-ray source counts, the stacked X-ray spectrum, and the optical identifications. A total of 188 X-ray sources were detected: 174 in the 0.5-7.0 keV band, 154 in the 0.5-2.0 keV band, and 113 in the 2.0-7.0 keV band. The X-ray source counts were derived and compared with the 172 ks exposure LALA Bootes field (available as the LALABOOCXO table in Browse). Interestingly, the authors find consistent hard-band X-ray source density, but a (36 +/- 12)% higher soft-band X-ray source density in the Cetus field. The weighted stacked spectrum of the detected X-ray sources can be fitted by a power law with photon index Gamma = 1.55. Based on the weighted stacked spectrum, the authors find that the resolved fraction of the X-ray background drops from (72 +/- 1)% at 0.5-1.0 keV to (63 +/- 4)% at 6.0-8.0 keV. The unresolved spectrum can be fitted by a power law over the range 0.5-7 keV, with a photon index Gamma = 1.22. Optical counterparts are also presented for 154 of the X-ray sources, down to a limiting magnitude of r&#39; = 25.9 (Vega), using a deep r&#39;-band image obtained with the MMT.

MESSENGER E/V/H GRNS 3 GAMMA RAY SPECTROMETER CALIBDATA V1.0

Abstract : This data set consists of the MESSENGER GRS calibrated observations (CDRs) and the reduced data product (RDR). The GRS experiment is a gamma ray spectrometer designed to observe spectra of gamma rays emitted from Mercury's surface in the energy range from 0.1 to 10 MeV. There are seven basic GRS CDR data products: the Ge raw spectra data (GRS_CAL_RAW), the anti-coincidence spectra data (GRS_CAL_AC), the shield spectra data (GRS_CAL_SH, GRS_CAL_SH2, GRS_CAL_SH3), the shield count rate (GRS_CAL_SCR) and the engineering data (GRS_ENG). There is one GRS RDR product (GRS_RDR_SUM), a spectral sum of the GRS_CAL_RAW and GRS_CAL_AC spectra.

Swift BAT Transient Monitoring Catalog

The SWBATMONTR database table records high-level information of the lightcurves from the sources monitored with the Burst Alert Telescope (BAT) on board of Swift. The Swift/BAT Monitoring Program is aimed at (1) the discovery of new transient X-ray sources, (2) the detection of outbursts or other changes in the flux of known X-ray sources, and (3) the generation of lightcurves of more than 1000 sources spanning the entire Swift lifetime. Swift is a NASA mission with international participation dedicated to the gamma-ray burst study. It carries three instruments. The BAT is the large field of view instrument and operates in the 10-300 keV energy band; and two narrow field instruments, XRT and UVOT, that operate in the X-ray and UV/optical regime, respectively. The BAT monitoring the sky in the field of view and provides alerts when detecting a burst of flux coming from a source in the field of view. The BAT monitoring lightcurves are generated by the BAT team over the course of the Swift mission. The HEASARC ingests these data in the archive and generates this database table by collecting high-level information from the data. The lightcurves are renamed to use a consistent naming convention, and the FITS header is updated by adding standard FITS keywords. This is a service provided by NASA HEASARC .

Byurakan/Hamburg/ROSAT Catalog of Optical IDs

This table contains the Byurakan/Hamburg/ROSAT Catalog (BHRC) of the optical identifications of X-ray sources. The BHRC includes all 2791 X-ray sources from the ROSAT Faint Source Catalog (ROSAT-FSC, CDS Catalog &lt;IX/29&gt;) with galactic latitude |b| &gt;= 30 degrees, declination &gt;= 0 degrees, and ROSAT PSPC count rate CR &gt; 0.04 ct/s. The optical identifications were carried out using the Hamburg Quasar Survey (HQS) digitized spectroscopic plates, the DSS1 and DSS2 (blue, red, and IR) images, the MAPS photometric data, the USNO-B1.0 (for proper motion), the NVSS and FIRST radio, and the IRAS and 2MASS infrared catalogs. From the DSS images, positional, brightness, color, extension, variability, and proper-motion information, the optical-to-X-ray positional offsets were obtained and a morphological classification was made. Available SIMBAD and NED data were also utilized. Cross-correlations were made with AGN, white dwarf, and cataclysmic variable catalogs (322, 8 and 7 associations, respectively). The authors managed to identify 97% of the sources (2696/2791 sources) that are associated with 3202 optical objects. 2248 X-ray sources have a single optical counterpart, 144 have a double or multiple optical counterpart (binaries, galaxy groups, etc.), and 304 have ambiguous identifications (some of the latter might actually be blends of two X-ray sources that were not resolved by ROSAT). The QSOs and AGN represent the largest group of X-ray counterparts (56.2%); bright stars (including late-type stars, but excluding WDs and CVs) are counterparts for 33.2% of the sources, and bright galaxies and groups of galaxies comprise 9.2%. A number of close galaxy pairs (possibly interacting/merging galaxies) are found as counterparts for X-ray sources (3.0%), as well as 1.0% WDs and 0.4% CVs. The BHRC may be used for the selection and study of samples of the various classes of X-ray emitters: the table gives all the available multiwavelength data for the identified sources.

ROSAT All-Sky Survey and SDSS DR5 Sample of X-Ray Emitting AGN

This table contains further results of a program aimed at yielding ~ 10&lt;sup&gt;4&lt;/sup&gt; fully characterized optical identifications of ROSAT X-ray sources. The program employs X-ray data from the ROSAT All Sky Survey (RASS) and both optical imaging and spectroscopic data from the Sloan Digital Sky Survey (SDSS). RASS/SDSS data from 5740 deg&lt;sup&gt;2&lt;/sup&gt; of sky spectroscopically covered in SDSS Data Release 5 (DR5) provide an expanded catalog of 7000 confirmed quasars and other active galactic nuclei (AGN) that are probable RASS identifications. Again, in this expanded catalog the identifications as X-ray sources are statistically secure, with only a few percent of the SDSS AGNs likely to be randomly superposed on unrelated RASS X-ray sources. Most identifications continue to be quasars and Seyfert 1 galaxies with 15 &lt; m &lt; 21 and 0.01 &lt; z &lt; 4, but the total sample size has grown to include very substantial numbers of even quite rare AGN, e.g., it now includes several hundreds of candidate X-ray-emitting BL Lac objects and narrow-line Seyfert 1 galaxies. In addition to exploring rare subpopulations, such a large total sample may be useful when considering correlations between the X-ray and the optical and may also serve as a resource list from which to select the ``best&#39;&#39; object (e.g., the X-ray-brightest AGN of a certain subclass at a preferred redshift or luminosity) for follow-up X-ray spectral or alternate detailed studies. Much more information on the SDSS is available at the project&#39;s web site at &lt;a href="http://www.sdss.org/"&gt;http://www.sdss.org/&lt;/a&gt;. This table was created by the HEASARC in February 2007 based on the combination of the electronic versions of tables 1 through 6 from the above reference which were obtained from the electronic AJ website. It replaces a previous version containing the results presented by Anderson et al. (2003, AJ, 126, 2209) which were based on a cross-correlation of the RASS with optical data from very early on in the SDSS program, e.g., extending back to the &#39;Early Data Release&#39; before SDSS photometric calibrations were complete.

HEAO 1 A2 LED Catalog

The HEAO 1 A-2 LED Catalog of High-Energy X-ray Sources is the result of a study of the diffuse X-ray sky over the bands of X-ray energies 0.18-0.44 keV and 0.44-2.8 keV from August 1977 until January 1979 using data obtained with the A-2 Low Energy Detector on the HEAO 1 satellite. The HEAO A-2 Experiment was primarily designed for studying the diffuse X-ray background; however, it was also capable of studying point sources to good sensitivity. The detectors surveyed over 95 percent of the sky in the spectral bands listed above to typical limiting sensitivities of 1x10**-11 and 3x10**-11 respectively. Using a significance criterion of 6 sigma for existence, 114 sources are cataloged. The catalog contains a list of all counterpart identifications and a cross-reference to all HEAO 1 A-2 LED team publications on the catalog sources complete through the end of 1981. The identified sources fall into several categories, primarily dependent on observing energy interval. In the 1 KeV band the sources include: 20 galactic stellar sources, 19 extragalactic sources, 13 SNR&#39;s, 11 galactic bulge sources, 2 globular cluster sources, and 2 previously reported sources without optical counterparts. In the .25 KeV band the sources include: 24 galactic stellar objects, 12 extragalactic sources, 5 SNR&#39;s, 1 bulge source, and 1 globular cluster source.
