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 2dpsf files were not installed.
