Method
The Aspect/Attitude and Eventrate files contain a set of
housekeeping parameters as a function of spacecraft clock time.
The names of the parameters are detailed in the EXSAS users guide,
if you can get hold of a copy. Some of the more important
ones are:
EE_MV* - the Master veto rate
EE_AXE* - the accepted event rate
ASP_ERR* - the aspect error
*These names are for MPE PSPC data files.
Each of these are stored as HDS arrays in the above files.
Limits may be set on up to ten of these parameters. The program
merges the time ranges excluded by each of these limits and
inverts to produce a file of "GOOD" time windows over which the
data can be sorted. The file produced, contains a list of MJDs and
should be entered as the response to the prompt for TIMRANGE in
XSORT.
