- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table is an associated to the GRBs Catalog and lists the parameters that define the localization region if the region is a circle. For a given GRB the localization can be provided by different observatories with different region types or by the same region type with different parameters. The different region types reported in literature are the following: circle, annulus, box, dual, annulus intersect, irregular, and intersect. This table contains the description only for the circle region type, the other types are stored in separate tables. The circle region is described by a center given in RA and Dec, and a radius given in degrees. The measurements are reported as found in literature and any differences or remarks are included in one of the table parameter (local_notes). The literature references are provided in the GRBs Catalog main table which is linked to this region table. This table was ingested by the HEASARC in June 2008 based on electronic versions obtained from the author(s), who compiled the catalog in 2005. This is a service provided by NASA HEASARC .

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table is an associated to the GRBs Catalog and lists the parameters that define the localization region if the region is dual (two error regions). For a given GRB the localization can be provided by different observatories with different region types or by the same region type with different parameters. The different region types reported in literature are the following: circle, annulus, box, dual, annulus intersect, irregular, and intersect. This table contains the description only for the dual region type, the other types are stored in separate tables. The dual region type is for GRBs that had the localization defined by two error circle regions. The dual regions are defined by the centers of the two circle region given in RA and Dec and their radii given in degrees. The measurements are reported as found in literature and any differences or remarks are included in one of the table parameter (local_notes). The literature references are provided in the GRBs Catalog main table which is linked to this region table.

- Catalog of Gamma-Ray Bursts: Fluxes and Fluences
- Short Name:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table is an associated to the GRBs Catalog and lists the fluxes and fluences of the GRBs. Each record contains a flux and a fluence as detected by an observatory for a given energy range. If for a given GRB flux and fluence are reported by several observatories, the table contains separate records for each of the observatory. If an observatory measured flux and fluence in different energy bands, the table contains separate record for each energy band. The table therefore can contain several records associated to a given GRB depending on the number of observatories providing measurements and on the different energy bands. The measurements are reported as found in literature with the units used by the original authors and not always flux and fluence (and their errors) are both present. The literature references are provided in the GRBs Catalog main table which is linked to this flux table. This table was ingested by the HEASARC in June 2008 based on electronic versions obtained from the author(s), who compiled the catalog in 2005. This is a service provided by NASA HEASARC .

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table is an associated to the GRBs Catalog and lists the parameters that defines the box region derived from the intersection between the IPN annulus and a region from a different observatory. For a given GRB the localization can be provided by different observatories with different region types or by the same region type with different parameters. The different region types reported in literature are the following: circle, annulus, box, dual, annulus intersect, irregular, and intersect. This table contains the description only for the region type intersect, the other types are stored in separate tables. This localization region consists of a box derived from the intersection of the IPN annulus with the region determined by a different observatory. The table lists the corners of the final box intersection and the parameters that defined the IPN annulus (center, radius and half-width). The region of the other observatories that intersect with the IPN annulus is listed with the record for this GRB associated with the other observatory. The measurements are reported as found in literature and any differences or remarks are included in one of the table parameter (localization_notes). The literature references are provided in the GRBs Catalog main table which is linked to this region table.

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table is an associated to the GRBs Catalog and lists the parameters that define an 'irregular' region as the localization region. For a given GRB the localization can be provided by different observatories with different region types or by the same region type with different parameters. The different region types reported in literature are the following: circle, annulus, box, dual, annulus intersect, irregular, and intersect. This table contains the description only for the irregular region type, the other types are stored in separate tables. The 'irregual' region are from the Kippen et al. (1998). This localization region consist of a short thin arc segment derived from a COMPTEL localization combined with an IPN localization where the most likely position corresponds to the maximum obtained from the integral distribution. The COMPTEL localization consists of a circle error region centered at the most likely position within that region. The measurements are reported as found in literature and any differences or remarks are included in one of the table parameter (local_notes). The literature references are provided in the GRBs Catalog main table which is linked to this region table.

- Catalog of High-Mass X-Ray Binaries in the Galaxy (Dynamic Version)
- Short Name:
- HMXBCAT2
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- High-Mass X-ray Binaries (HMXBs) are a particular class of high-energy sources which require multi-wavelength observational efforts to be properly characterized. New identifications and refinement of previous measurements are regularly published in the literature by independent teams of researchers and could, once collected in a catalog, offer a tool to facilitate further studies on HMXBs. The authors aim to update on previous instances of catalogs of HMXBs in the Galaxy, and provide the community easy access to the most complete set of observables on Galactic HMXBs. On top of the fixed version that is available in VizieR, they also aim to host and maintain a dynamic version that can be updated upon request from users, and where any modification will be logged. Using previous catalogs of HMXBs supplemented by listings of hard X-ray sources detected in the past 20 years, the authors produce a base set of HMXBs and candidates by means of identifier and sky coordinate cross-matches. They query SIMBAD for unreferenced HMXBs. They search for as many hard X-ray, soft X-ray, optical and infrared counterparts to the HMXBs as we can in well-known catalogs and compile their coordinates. Each HMXB is subject to a meticulous search in the literature to find relevant measurements and their original reference. The authors provide a catalog of HMXBs in the Galaxy with their best known coordinates, companion star spectral type, systemic radial velocities, component masses, orbital period, eccentricity and spin period when available. This catalog also provides the coordinates and identifiers for each counterpart found from hard X-rays to near-infrared, including counterparts from the recent Gaia DR3 catalog. This catalog was created from data-mining the published literature. It takes into account information available through 2022. Values for binary parameters are joined with a reference in which the value was derived. Position data for which the authors have manually found a counterpart also have a specific reference; if not, then the data comes directly from the corresponding catalog. This database table was first created by the HEASARC in October 2023, based on the 2023-09 version of this catalog, found from the <a href="https://binary-revolution.github.io/HMXBwebcat/">Binary rEvolution website</a>. It is automatically updated in the HEASARC database within a few days of a new version being released on that website. This is a service provided by NASA HEASARC .

- Catalog of High-Mass X-Ray Binaries in the Galaxy (4th Ed.)
- Short Name:
- HM XRB
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains the 4th edition of the Catalog of High-Mass X-Ray Binaries (HMXBs) in the Galaxy. The catalog contains source name(s), coordinates, finding charts, X-ray luminosities, system parameters, and stellar parameters of the components and other characteristic properties for 114 HMXBs, together with a comprehensive selection of the relevant literature. The aim of this catalog is to provide some basic information on the X-ray sources and their counterparts in other wavelength ranges (gamma-rays, UV, optical, IR, radio). About 60% of the high-mass X-ray binary candidates are known or suspected Be/X-ray binaries, while 32% are supergiant/X-ray binaries. Some sources, however, are only tentatively identified as high-mass X-ray binaries on the basis of their X-ray properties similar to the known high-mass X-ray binaries. Further identification in other wavelength bands is needed to finally determine the nature of these sources. In cases where there is some doubt about the high-mass nature of the X-ray binary this is noted. Literature published before 1 October 2005 has, as far as possible, been taken into account.

- Catalog of Infrared Observations (CIO), Edition 5
- Short Name:
- CIO
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Fifth Edition of the Catalog of Infrared Observations (CIO) comprises a summary of infrared astronomical observations published in the scientific literature from 1965 through 1997 in the wavelength range 1 micrometer (= 1 micron = 1 um) to 1 millimeter (= 1 mm). This catalog contains infrared observational data for sources outside the Solar System, constructed through a search of the most active scientific journals, IR surveys and catalogs. To date, about 6200 journal articles and 10 major survey catalogs have been included in the database from which this catalog was constructed. The catalog in its original form contains 374,653 individual observations of about 62,000 different infrared sources. More than 8000 of these sources are identifiable with visible objects. For sources with no published IR source position, a nominal position may have been given based on other sources. Nominal positions are usually the best available, but not necessarily the true IR positions. The HEASARC has removed 1136 of the 374,653 entries in the catalog in its original form for which there was no positional information, leaving 373,517 remaining entries in this HEASARC-realized version. The 1136 entries that were removed are listed in the file: <a href="https://heasarc.gsfc.nasa.gov/FTP/heasarc/dbase/misc_files/infrared/deleted_entries.txt">https://heasarc.gsfc.nasa.gov/FTP/heasarc/dbase/misc_files/infrared/deleted_entries.txt</a> In addition to the main catalog, the creators of CIO also generated other files, e.g., bibliographical files, an index file, etc., which are available via the web (in the form of gzipped ASCII files) in the directory: <a href="https://heasarc.gsfc.nasa.gov/FTP/heasarc/dbase/misc_files/infrared/">https://heasarc.gsfc.nasa.gov/FTP/heasarc/dbase/misc_files/infrared/</a>. The bibliographical files (refauth.data.gz refchron.dat.gz, and refs.dat.gz) link observations in the catalog with references to the original articles published in the literature (these references give the standard information plus the full titles). The Index of Infrared Source Positions is contained in the file names.dat.gz and is ordered alphabetically by source name: for sources with no published IR source position, a nominal position (usually the best available, but not necessarily the true IR position) may have been given based on other sources. Nominal position references are indicated in the index. This version of the 5th Edition of the Catalog of Infrared Observations was created by the HEASARC in April 2001 based on ADC/<a href="https://cdsarc.cds.unistra.fr/ftp/cats/II/225">CDS catalog <II/225></a>. Duplicate entries were removed in June 2019. This is a service provided by NASA HEASARC .

- 7C Catalog 151-MHz Survey Final Unified Source Catalog
- Short Name:
- UC7C151MHZ
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains a final unified catalog for the 7C survey at 151 MHz with a spatial resolution of 70 x 70cosec(Dec) arcsec<sup>2</sup>. This has been constructed by amalgamating the existing catalogs derived from individual fields imaged at this resolution and eliminating redundancy in regions of mutual overlap. This was a non-trivial procedure because the flux in multiple-component sources may be fitted differently on alternative images, owing, for example, to differences in local noise and beam distortion. The final catalog as published thus produced contains 43683 sources. (Note that the HEASARC removed one duplicate source entry for '7C 083231.6+262635' since it had two entries, which were identical except that in one the beam-fitted flux density S<sub>bf</sub> was 834 mJy/beam, while, in the other entry now removed, S<sub>bf</sub> was 840 mJy/beam). Separate final catalogs have been previously published for the 7C Galactic Plane 7CG survey (available as the HEASARC table GP7C151MHZ), and the lower-resolution survey of the low-declination strip 9<sup>h</sup> < RA < 16<sup>h</sup>, 20<sup>o</sup> < Dec < 35<sup>o</sup> (available as the HEASARC table LD7C151MHZ). The individual catalogs for about 40 of the 96 regions contributing to the total have already been published, together with full details of the methodology, in MNRAS or A&AS: <pre> Reference Region Lacy et al. 1995, MNRAS, 276, 614 92 Visser et al. 1995, A&AS, 110, 419 93 Pooley et al. 1998, MNRAS, 298, 637 94-96 Riley et al. 1999, MNRAS, 306, 31 1-33 </pre> and these data are also available via the MRAO website: <a href="http://www.mrao.cam.ac.uk/surveys/7C/">http://www.mrao.cam.ac.uk/surveys/7C/</a> Individual catalogs for the remaining 58 regions by Riley et al. (regions 34-91) were released electronically via the MRAO website in November 2001. These include a re-analysis of data originally published in rather a different parametrization by McGilchrist et al. 1990, MNRAS, 246, 110. The regions re-analyzed are those numbered 41, 44, 59, 60, 62 and 63 and they supersede McGilchrist's 1990 publication. The RA x Dec coverage, the average rms noise, the flux density of the faintest source listed and the completeness limit for each of the individual regions contributing to the final catalog are given in the table <a href="http://cdsarc.u-strasbg.fr/ftp/cats/J_MNRAS/382/1639/regions.dat">http://cdsarc.u-strasbg.fr/ftp/cats/J_MNRAS/382/1639/regions.dat</a>. For further details of the surveys and data analysis procedures please refer to the published papers referenced above and other references contained therein.

- 9C Continued 15-GHz Ryle Telescope Survey of VSA Fields Source Catalog
- Short Name:
- RT9CC15GHZ
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The 9C (9th Cambridge) survey of radio sources with the Ryle Telescope at 15.2 GHz was set up to survey the fields of the cosmic microwave background telescope, the Very Small Array (VSA). In their first paper (Waldram et al. 2003, MNRAS, 342, 915), the authors described three regions of the survey, constituting a total area of 529 deg<sup>2</sup> to a completeness limit of ~ 25 mJy. In this follow-up, they present results from a series of deeper regions, constituting a total area of 115 deg<sup>2</sup> complete to ~ 10 mJy and of 29 deg<sup>2</sup> complete to ~ 5.5 mJy. The authors have investigated the source counts and the distributions of the 1.4 to 15.2 GHz spectral indices for these deeper samples. The whole catalog of 643 sources is contained in the present table. Down to their lower limit of 5.5 mJy, the authors detect no evidence for any change in the differential source count from the earlier fitted count above 25 mJy, n(S) = 51(S/Jy)<sup>-2.15</sup> Jy<sup>-1</sup> sr<sup>-1</sup>. They matched both their new and earlier catalogues with the NRAO VLA Sky Survey (NVSS) catalogue at 1.4 GHz and selected flux-limited samples at both 15 and 1.4 GHz. As they expected, they found that the proportions of sources with flat and rising spectra in the samples selected at 15 GHz are significantly higher than those in the samples selected at 1.4 GHz. In addition, for 15-GHz samples selected in three flux density ranges, they detect a significant shift in the median value of the 1.4 to 15.2 GHz spectral index: the higher the flux densities, the higher the proportions of sources with flat and rising spectra. In the area complete to ~ 10 mJy, the authors find five sources between 10 and 15 mJy at 15 GHz, amounting to 4.3 per cent of sources in this range, with no counterpart in the NVSS catalogue. This implies that, had they relied on the NVSS for locating their sources, they could have missed a significant proportion of them at low flux densities. These results illustrate the problems inherent in using a low-frequency catalog to characterize the source population at a much higher frequency and emphasize the value of a blind 15.2-GHz survey. This table was created in November 2010 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/404/1005">CDS catalog J/MNRAS/404/1005</a> file 9c_cont.dat.
