Bugs: combine_grating_spectra


Bugs

Problems when setting outroot the same as mktgresp

Users cannot use the same outroot value for both combine_grating_spectra and mktgresp. Depending on the other parameters, this can result in the same file names being created by both scripts for different data products which can then lead to unusual errors. It may cause combine_grating_spectra to error out with a message about missing files.


Bugs fixed in CIAO 4.14

The following is a list of bugs that were fixed in the CIAO 4.14 software release.

Incorrect NUMGRP and NUMELT keywords

The addresp tool is not updating the NUMGRP nor the NUMELT keywords in the output file to match the actual values in the MATRIX's N_GRP and N_CHAN columns. It is simply copying those keywords from the 1st file to the output file. These incorrect values have shown to cause problems with XSPEC v 12.11.0.
