Swift Calibration Files

This page contains a summary of the Swift Calibration files which are currently in the Swift Calibration Database (CALDB). For each instrument, each table links to the latest CALDB releases, from where individual files can be downloaded as well as the CALDB index file. The tables also link to the current CALDB tar files which users can install on their local machines. Note: The tar files for each of the instruments already include the Swift common calibration products.
Instructions for installing the CALDB for Swift or other missions are available from the CALDB Installation page. Note that the easiest way to access calibration data for Swift or other HEASARC-supported missions is via remote access.

Caldb access for Swift requires an updated version of the caldb.config file which is available at https://heasarc.gsfc.nasa.gov/FTP/caldb/software/tools .Please replace your current $CALDBCONFIG file with this updated version.
