In addition to the comments, many questions exist regarding merging
files over from different exposures, and the handling of EXPOSURE, GTI and
BADPIX extensions.
In merging event files from different EPIC instruments (i.e. MOS and
pn), the event attribute columns should not be merged, as different
instruments assign different meanings to the same bits. Merging across
different instruments should be done after good events have been selected
(this is related also to the point above in the comments).
