CIAO 3.2.1 Release Notes


The CIAO 3.2.1 patch contains updated versions of acis_build_badpix and

acis_run_hotpix
. For more information on using these tools, please see the
Identify ACIS Hot Pixels and Cosmic Ray Afterglows thread, which has been updated to reflect the changes in this release.

  • acis_build_badpix is updated to write a correct header in the output bad pixel file.

  • acis_run_hotpix is updated to accept a parameter block file (pbkfile parameter). The ahelp file for the tool has been updated.

Make sure to delete any existing parameter file (acis_run_hotpix.par) in ~/cxcds_param so that you pick up the CIAO 3.2.1 default version, which has a new parameter (pbkfile).

If you created a new bad pixel file with acis_run_hotpix in CIAO 3.2 and the tool did not report any errors, it is not necessary to recreate the file in CIAO 3.2.1.
