Future developments

• 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).
