Description
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 .
