The CALCHDMSTR database table records high-level information of the lightcurves obtained with the CHarge Detector (CHD), the top layer of the calorimeter instrument on the CALorimetric Electron Telescope (CALET) mission. CALET is a Japanese mission led by JAXA, in collaboration with the Italian Space Agency (ASI) and NASA, and is dedicated to the study of high energy cosmic rays. CALET was launched on August 19, 2015, by a Japanese carrier, H2 Transfer Vehicle, and robotically installed on the Japanese Experiment Module-Exposed Facility (JEM-EF) on the International Space Station (ISS). CALET started scientific observations in October, 2015. The CALET CHD lightcurves are delivered by the CALET team in Japan as ASCII files to the DARTS archive located at ISAS (Japan). The HEASARC developed software to create the FITS versions of the lightcurves. This is run at DARTS, and the output is placed online at <a href="https://darts.isas.jaxa.jp/astro/calet/">https://darts.isas.jaxa.jp/astro/calet/</a>. The HEASARC hosts a copy of these lightcurves and generates this database table by collecting high-level information from the data. The Data and the database table are updated regularly during operation. This is a service provided by NASA HEASARC .
The CALGBMMSTR database table records high-level information of the observations obtained with the CALET Gamma-ray Burst Monitor (CGBM), the second scientific payload on the CALorimetric Electron Telescope (CALET) mission. The Gamma-ray Burst Monitor provides a broadband energy coverage from 7 keV to 20 MeV and simultaneous observations with the primary instrument CALET Calorimeter (CCAL) in the GeV - TeV gamma-ray range and with the Advanced Star Camera (ASC) in the optical for gamma-ray bursts (GRBs) and other X-ray/gamma-ray transients. CALET is a Japanese mission led by JAXA, in collaboration with the Italian Space Agency (ASI) and NASA, and it is dedicated to the study of high energy cosmic rays. CALET was launched on August 19, 2015, by a Japanese carrier, H2 Transfer Vehicle, and robotically installed on the Japanese Experiment Module-Exposed Facility (JEM-EF) on the International Space Station (ISS). CALET started scientific observations in October, 2015. The CALET GBM Team in collaboration with DARTS and HEASARC developed the FITS file structure for the GBM data and their archive. The CALET GBM data are delivered by the CALET GBM team in Japan to the DARTS archive located at ISAS (Japan). The HEASARC hosts a copy of these data and generates this database table by collecting high-level information from the data. The data and the database table are updated regularly during operation. The first data release includes PH and TH data. Event data and the image from the ASC are added in a second phase. This is a service provided by NASA HEASARC .
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 .
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 .
Catalog of Gamma-Ray Bursts: Annulus Intersect Regions
Short Name:
GRBCATINTA
Date:
07 Mar 2025
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 .
