- Catalog of Gamma-Ray Bursts: Dual Regions

- 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. 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: Fluxes and Fluences
- Short Name:

- Date:

- 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 .

- Catalog of Gamma-Ray Bursts: Intersect Regions
- Short Name:
- GRBCATINT
- Date:

- 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.

- Catalog of Gamma-Ray Bursts: Irregular Regions
- Short Name:
- GRBCATIRR
- Date:
- 07 Mar 2025
- 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.

- CGRO/COMPTEL Low-Level Data and Maps
- Short Name:

- Description:
- COMPTEL is both the name of the Imaging Compton Telescope on the Compton Gamma Ray Observatory (CGRO) and the name of this HEASARC database table which allows the user to select low-level data and maps produced by this instrument. Much more information on the COMPTEL instrument, data products, and data analysis techniques can be obtained from the Compton Observatory Science Support Center (COSSC) web site at <pre> <a href="https://heasarc.gsfc.nasa.gov/docs/cgro/">https://heasarc.gsfc.nasa.gov/docs/cgro/</a> </pre> and from the article in Legacy No. 7 on the HEASARC CGRO Data Archive <pre> <a href="https://heasarc.gsfc.nasa.gov/docs/journal/cgro7.html">https://heasarc.gsfc.nasa.gov/docs/journal/cgro7.html</a> </pre> Interactions in COMPTEL occur in a two stage process: First, a Compton collision occurs in one of seven (low-Z) liquid scintillators and is usually then completely absorbed in one of fourteen (high-Z) NaI(Tl) scintillators. The unusual aspect of this detector is that the location of the gamma-ray on the sky is given by an annulus and not a point. The correlation of many events enables the localization of point sources or the creation of sky maps. Time-of-flight measurements, pulse shape discrimination and anti-coincidence shields are used to reject background events. COMPTEL has a wide field of view (about 1 steradian, equivalent to a FWHM of about 40 degrees), an angular resolution under optimal conditions of about 1 degree, and an energy resolution that ranges from 5-10% at 1 MeV. During Phase 1 of the CGRO mission, COMPTEL completed the first all-sky survey in the energy range of 0.75-30 MeV (in four energy bands). In addition, COMPTEL can measure energy spectra of solar flares or bright cosmic gamma-ray bursts between 0.1-10 MeV, and neutrons from solar flares. This is a service provided by NASA HEASARC .
