Download CALDB 4.9.1
Latest Update: 03 April 2020
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. Users of earlier versions of CIAO may use CALDB 4.8.5 or earlier.
CIAO 4.11 and earlier users analyzing ACIS data should NOT upgrade to CALDB 4.9.1. While the new format of the temperature dependent CTI correction calibration files can be read by earlier versions CIAO, the higher order coefficients are not included. The new columns are ignored resulting in an inaccurate temperature adjustment being applied.
CIAO 4.12 HRC users must update to CALDB 4.9.1 due to the changes in the degap file. Similarly, CALDB 4.9.1 should not be used with earlier versions of CIAO. In both cases doing so will trigger an earlier degap algorithm that performs badly at the edges of the plates.
