The CALCHDMSTR database table records high-level information of the particle rates 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 particle rates as function of time 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 version of these time-particle rate files. The software 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 files 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 .
