- Title:
- Cataclysmic Variables Catalog (2006 Final Edition)
- Short Name:
- CVs
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This catalog contains data for a large number of objects that have been classified as cataclysmic variables (CVs) as well as a smaller number of objects that are now not considered to be cataclysmic variables, but were originally classified erroneously as such. As of 2000 December, 40% of the objects in this catalog were dwarf novae, with another 30% being novae, and the rest being mostly nova-like variables; also as of this date, a large fraction (90%) of the CVs had references to published finding charts, while 64% of the objects had published spectra. The catalog includes coordinates measured in the reference frame of the Hubble Space Telescope Guide Star Survey for non-novae and from the literature for novae. Also given are the variability type, the magnitude range, orbital periods, flags indicating the existence of relevant space-based observational datsets, references to finding charts and spectroscopy, the galactic latitude and longitude, and the year of outburst (for novae). This edition also includes plate identification information for the coordinate measurements, and a reference to the classification. The Catalog and Atlas of Cataclysmic Variables (Downes et al. in 2001, PASP, 113, 764 and <a href="http://archive.stsci.edu/prepds/cvcat/">http://archive.stsci.edu/prepds/cvcat/</a>) presented here is the ASCII Report mentioned in Section 2.1 of the PASP paper, and is similar to the previously published versions of the CV Catalog (e.g., Downes, Webbink and Shara 1997, PASP, 109, 345, Table 1). The online version of the CV Catalog at <a href="http://archive.stsci.edu/prepds/cvcat/">http://archive.stsci.edu/prepds/cvcat/</a> contains additional data on these systems not included in this database, including finding charts. For a complete authoritative and up-to-date description of the CV Catalog, refer to <a href="http://archive.stsci.edu/prepds/cvcat/description.html">http://archive.stsci.edu/prepds/cvcat/description.html</a>, from which the HEASARC has constructed this help file.

- Title:
- Catalog of AGN in the XMM-Newton Archive
- Short Name:
- CAIXA
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table comprises CAIXA, the "Catalog of AGN In the XMM-Newton Archive". It consists of all the radio-quiet, X-ray unobscured (N<sub>H</sub> < 2 x 10<sup>22</sup> cm<sup>-2</sup>) active galactic nuclei (AGN) observed by XMM-Newton in targeted observations, whose data were public as of March 2007. With its 156 sources, this is the largest catalog of high signal-to-noise X-ray spectra of AGN. All the EPIC pn spectra of the sources in CAIXA were extracted homogeneously, and a baseline model was applied in order to derive their basic X-ray properties. These data are complemented by multiwavelength data found in the literature: black hole masses, full width half maximum (FWHM) of H(beta), radio and optical fluxes. In their paper, the authors describe their homogeneous spectral analysis of the X-ray data in CAIXA and present all the results for the parameters adopted in their best-fit models. This table was created by the HEASARC in March 2009 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/495/421">CDS catalog J/A+A/495/421</a> files table1.dat, table2.dat and table3.dat.

- Catalog of Galactic OB Stars
- Short Name:
- GALOBSTARS
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- An all-sky catalog of Galactic OB stars has been created by extending the Case-Hamburg Galactic Plane Luminous Stars surveys to include 5,500 additional objects drawn from the literature. This work brings the total number of known or reasonably suspected OB stars to over 16,000. This catalog contains UBV photometry and MK spectral type classifications for these objects as well as radial velocities. This project originated in the summer of 1991 when the author began compiling a cross-reference catalog and tabulation of published UBVbeta photometry for stars listed in Stephenson and Sanduleak's Luminous Stars (LS) in the Southern Milky Way Catalog (<a href="https://cdsarc.cds.unistra.fr/ftp/cats/III/43">CDS Cat. III/43</a>). This database was published in July 1993 (Reed 1993, ApJS, 87, 367) and was subsequently expanded to include compilations of published MK classifications (Reed & Beatty 1995, ApJS, 97, 189), 4-color photometry (Read 1996, A&AS, 117, 313), and radial velocities (Reed & Kuhna 1997, AJ, 113, 823) for these objects. In mid-1997 the project was again expanded to include UBVbeta photometry for stars listed in the Northern-hemisphere volumes of the "Case-Hamburg" (<a href="https://cdsarc.cds.unistra.fr/ftp/cats/III/76">CDS Cat. III/76</a>) surveys (Reed 1998, ApJS, 115, 271); MK classifications for the Northern stars were similarly compiled and made electronically available to interested parties, though they were not formally published. Most of the LS objects are OB stars, but there are as well a number of A, F, and G supergiants and a few white dwarfs and Wolf Rayet stars. These surveys reached a limiting photographic magnitude of ~13.5, and were based on objective-prism surveys of dispersion 580 Angstrom/mm at H-gamma. OB stars is here taken to mean main-sequence stars down to temperature class B2 and more luminous ones down to temperature class B9. The original Case-Hamburg surveys (about 12,000 stars) also include some 2,000 evolved A-G stars, along with some white dwarfs, planetary nebulae, and Wolf-Rayet stars. It is worth noting that the definition of an OB star is not universal; for example, Vanbeveren et al. (1998, in "The Brightest Stars") define them as O-B2 V-IV, O-B3 III, O-B4 II, and all OBA Ib, Iab, Ia, and IaO stars. This table was created by the HEASARC in September 2017 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/V/125">CDS Catalog V/125</a> files obcat.dat, obmk.dat, obubvbet.dat and radvel.dat.

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This is a catalog of galaxies observed in the X-ray band with the Einstein Observatory imaging instruments, the Imaging Proportional Counter (IPC) and the High Resolution Imager (HRI). The catalog comprises 716 observations of 493 galaxies, including those that were targets of pointed observations, and galaxies from the Revised Shapley-Ames (RSA) Catalog of Bright Galaxies and the Second Revised Catalog (RC2) Catalog of Bright Galaxies that were serendipitously included in Einstein fields, plus X-ray data on 4 other galaxies (LMC, SMC, M 31 = NGC 224, and M 32 = NGC 221) taken from the literature, for a total of 720 entries. A total of 450 of these galaxies were imaged well within the instrumental fields, resulting in 238 detections and 212 3-sigma upper limits. The other galaxies were either at the edge of the visible field of view or were confused with other X-ray sources. This database was created by the HEASARC in January 2002 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/80/531">CDS Catalog J/ApJS/80/531</a>, tables gxatlas.dat and gxfluxes.dat.

- Catalog of Gamma-Ray Bursts
- Short Name:
- GRBCAT
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This GRBs Catalog (GRBCAT) records high level information of the GRBs detected since their discovery in 1967. The catalog has been created using publications that report lists of GRB detections. These are mostly papers already published in refereed journals, unpublished papers, and PhD thesis presenting lists of GRBs. GRBCAT includes also compilation of bursts that were already present in the HEASARC database system. The catalog is organized with a main table reporting general information for each GRB and additional tables linked to the main table where specific information for the flux and the region of detection are reported. Afterglow measurements are also recorded in a separate table for all bursts detected after May 11 1996. The main table for each GRB contains an entry for each satellite that reports a detection with either a flux and/or position measurement. Therefore for a given GRB there are multiple records if the GRB was detected by more than one satellite. The associated flux table contains an entry for each flux and fluence values reported in literature for a given energy band. The positional information is reported via different tables each dedicated to a specific region of detection. The region descriptions are the following : circle, annulus, box, dual, annulus intersect, irregular, and intersect. The associated afterglow table contains position, intensity and redshift measurements taken after the discovery of the GRB. There are several records associated to a given GRB/afterglow since several observatories collected data on that position. The main table and the associated tables are updated when a new GRB and/or afterglow measurements are reported. 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 .

- Catalog of Gamma-Ray Bursts: Afterglows
- Short Name:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The GRB Afterglow table contains intensity and redshift measurements obtained with ground based telescopes or with space based observatories carried out after the detection of the GRBs. The catalog has been created using information from journal publications, IAU circulars, and GCN notices, and records afterglow measurements for bursts detected after May 1996. Each record within this catalog is dedicated to a specific measurement of an afterglow made with an observatory. Therefore for a given GRB, there are several entries reporting afterglow measurements from the different observatories. This catalog is linked to the main GRB catalog and it is updated when a new GRB and/or afterglow measurements are reported. 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 an intersection of annuli. 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 annuli intersect region type, the other types are stored in separate tables. This localization region consists of in the intersection up to three annuli. Each annulus is described by a center given in RA and Dec, the radius of the annulus and by the half- width of the annulus. 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 .

- Description:
- This table is an associated to the GRBs Catalog and lists the parameters that define the localization region if the region is a box. 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 box region type, the other types are stored in separate tables. The box region is defined by the corners of the box and a center given in RA and Dec. The number of corners to describe the box is up to six and for each corner the RA and Dec is provided. In a few cases, Laros et al. (1998) report "hybrid" boxes which are based on either the IPN and the BATSE-only or COMPTEL-only error regions were used. These hybrid boxes are defined by segments of one of the IPN annuli and an area. 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.
