This task reformats the EPIC ODF PN events list
into the file format required by subsequent off-line analysis.
epframes
converts frame numbers to event specific time tags.
It determines invalid events and frames and creates corresponding
GTI files per CCD. In addition, epframes
appends the CCD
specific exposure extension to the output event list. Optionally,
auxiliary information for cosmic ray analysis is collected.
