CALDB 4.6.2 Release Notes (release 9 Jul 2014)

[WARNING]
HRC-S QEU Index Issues

Two issues have been identified with the HRC-S QEU file selection, and will be fixed in CalDB 4.6.3.

  • An error in the CalDB index for HRC-S/LETG QEU files causes the wrong file to be selected for HRC-S observations since 2014 January 01. Subsequently, the calculated grating ARFs will underestimate fluxes by ~5%.

  • An error in the CalDB index for all HRC-S QEU files causes the incorrect QEU file to be selected for observations between 1999 September 01 to 2000 January 01. This error has been present since CalDB 4.4.0 (December 2012) and causes the calculated ARFs to overestimate fluxes by ~6.5%.

More information and workarounds to the issue can be found on the CALDB caveats page: "HRC-S QEU File Selection Problems".

Parameter Files

A summary of parameter files changes is provided in this section. Refer to the Tools and Analysis Scripts sections of these release notes for complete details.

We recommend deleting all the old parameter files or renaming the parameter-file directory before running any new version of CIAO to avoid conflicts. More information is available in the FAQ.
