Matching CIAO and CALDB Versions

CALDB 4.1.4 should not be used unless you are running CIAO 4.1 or later versions. CIAO 3.4 requires CalDB 3.5.5, available here.

Are your versions mismatched? Time to ugrade CIAO and CALDB!

Sample chkcif Errors

As explained in the Verify that the CALDB is Working section of the download instructions, if the PSF library has not been downloaded, then the HRC and ACIS branches will report errors when chkcif is run.

Note that the filename printed when the tool aborts is not necessarily the file that caused it to abort. Both of the following examples fail because the optional 2d_psf files were not installed.

Source the ciao.csh setup file (or your local equivalent) to begin. This sets up the $CALDB environment for testing.
