- 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 These are mostly papers already published in refereed journals, unpublished papers, and PhD thesis presenting lists of GRBs.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 .

- 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.

- 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 .

- 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.

- 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.

- Title:
- Gamma-Ray Bursts from the Interplanetary Network
- Short Name:
- GRB/IPN
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Interplanetary Network (IPN) is a group of spacecraft equipped with gamma-ray burst detectors used to localize gamma-ray bursts (GRB) and soft gamma repeaters (SGRs, or magnetars). The astronomical locations of GRBs are determined by the comparison of the arrival times of the event at the locations of the detectors used on different space missions. The precision is proportional to the distance of spacecraft separations, so that the localizational accuracy of a network with baselines of thousands of light-seconds can be equal or superior to that of any other technique. The primary disadvantage of the IPN method, however, is the 1-day to 1.5-day delay in the acquisition of data from all the spacecraft in the network. Interplanetary GRB networks have been in existence since 1977, contributing to the studies of various astrophysical gamma-ray transients, most notably GRBs and SGRs (soft gamma repeaters). The IPN3 began operations in 1990, with the launch of the Ulysses spacecraft. It was joined by the Compton Gamma Ray Observatory in 1991. Pioneer Venus Orbiter, Mars Observer, and the Italian X-ray astronomy satellite BeppoSAX were part of the network while they were operating. Twenty-six experiments or missions have joined the network so far. Today, the main spacecrafts contributing their data are Konus-WIND, Mars Odyssey, INTEGRAL, RHESSI, Swift, Agile, BepiColombo, and Fermi. XMM-Newton and MAXI are kept to record the cosmic ray and SGR but not used for triangulation because of the different energy range. The IPNGRB database table is derived from a list provided by Kevin Hurley <khurley@ssl.berkeley.edu>, based on the IPN3. The initial list also includes particles and solar events as well as unconfirmed SGRs and GRBs. The IPNGRB database includes only the observations of confirmed cosmic gamma-ray bursts and SGR since the launch of the Ulysses spacecraft. It is updated every time a new list is provided to the HEASARC. This HEASARC catalog is derived from the master list of IPN3 events provided by Kevin Hurley. He also provided a FORTRAN program that generates the list of selected events. The output of this program is run at GSFC and ingested into the HEASARC database system. Information on the IPN3 system is available at <a href="http://ipn3.ssl.berkeley.edu/">http://ipn3.ssl.berkeley.edu/</a>. <p> Information on the IPN can be found at <a href="http://heasarc.gsfc.nasa.gov/docs/heasarc/missions/ipn.html">http://heasarc.gsfc.nasa.gov/docs/heasarc/missions/ipn.html</a>. <p> In December 2021 Kevin Hurley passed away. He was one of the initiator of the IPN and its evolution. The last table provided is dated August 2021. This is a service provided by NASA HEASARC .
