What’s New

• 17 Nov 2025 : CALET CGBM Data at HEASARC Updated
  The HEASARC has added the CALET Gamma Ray Burst Monitory (CGBM) version 3.2a data to the archive, which contains data from the two Hard X-ray Monitor and Soft Gamma Ray Monitor instruments. The data is now complete up to the end of June 2025.
• 1 Aug 2025 : CALET Calorimeter Spectra at HEASARC Updated
  New CALET Calorimeter spectra data are available at the HEASARC for new elements.
• 31 Jul 2025 : CALET CGBM Data at HEASARC Updated
  The HEASARC has added the CALET Gamma Ray Burst Monitory (CGBM) version 3.2a data to the archive, which contains data from the two Hard X-ray Monitor and Soft Gamma Ray Monitor instruments. The data is complete up to the end of 2023, and includes trigger event files.
• GCN CALET-GBM Lightcurve Notices
  CALET GRB and Transient Light Curves are generated for trigger events such as gamma-ray bursts and transient high-energy sources, and updated routinely. The CALET-GBM instrument typically triggers around 12 times per month. Notices are sent out within minutes of detection by the onboard system, or within hours in the case of those detected with the ground-based processing systems.
• ADS Abstract Service CALET GCN notices
  The Astrophysics Data System (ADS) Abstract Service provides routinely updated and complete past listings of Gamma-ray burst Coordinates Network (GCN) notices for CALET.
• 2 May 2022 : CALET Calorimeter Spectra at HEASARC
  CALET Calorimeter spectra data are available at the HEASARC for electron, proton, and several selected elements.
• 4 Apr 2022 : CALET Calibration Data at HEASARC
  The first release of the CALET calibration data has been incorporated into the HEASARC caldb.config. To analyze CALET data with HEASOFT tools, please use this version of the caldb.config file.
• 2 Dec 2020 : CALET CGBM Data at HEASARC
  The CALET archive has been hosted at the DARTS/ISAS and a copy is now also available from the HEASARC. The HEASARC has added the CALET Gamma Ray Burst Monitory (CGBM) version 3 data to the archive, which contains spectral data from the two Hard X-ray Monitor and Soft Gamma Ray Monitor instruments, plus associated auxillary data and trend files. The archive is populated with the outputs of the data processing that occurs in Japan, and is synchronized weekly.
• 8 Jan 2020 : CALET Space Weather Data at HEASARC
  The CALET archive has been hosted at the DARTS/ISAS and a copy is now also available from the HEASARC. The HEASARC currently holds the calorimeter space weather data. The two archives are synchronized weekly. The archive is populated with the outputs of the data processing that occurs in Japan.
• May 2018 : CALET data at DARTS
  The CALET archive opens at the DARTS/ISAS with initial processing of the data.
