IXPE Calibration Files
This page contains a summary of the IXPE Calibration files which are currently in the Calibration Database (CALDB). The table links to the latest CALDB tar file and users can download it to install the IXPE CALDB locally.
Instructions for installing the CALDB for IXPE or other missions are available from the CALDB Installation page. The easiest way to access calibration data for IXPE or other HEASARC-supported missions is via remote access, which allows direct access the current HEASARC CALDB without having to install any calibration data locally.
Caldb access for IXPE requires the latest version of the caldb.config file (updated 20220314 or later) which is available at https://heasarc.gsfc.nasa.gov/FTP/caldb/software/tools. Please replace your current $CALDBCONFIG file with this updated version.
