This task merges EPIC event lists or additional files
(attitude, orbit) from two exposures (even from different
instruments),
pointing in the same or an adjacent
direction. Sky coordinates are (optionally) adjusted for attitude
errors and then reprojected to a common reference point.
The output files can be used by
evselect
and the higher
level detection and time analysis tasks.
