Installation notes

This page is only needed for manual installs, since the ciao-install script can be used to upgrade CALDB or add new packages (the ACIS and HRC background files).

CIAO 4.12 is required for the use of CALDB 4.9.0 or later. Users of earlier versions of CIAO may use CALDB 4.8.5 or earlier.

The CALDB contains all the calibration files required for Chandra data analysis. The CALDB can be downloaded, installed, and upgraded with the ciao-install script.

For more information on the CALDB, visit the CALDB website. Details on this release in particular are available from the CALDB 4.10.2 Release Notes.
