Examples

• merge set1=ev1.fits set2=ev2.fits outset=evout.fits (Merging two event files, reprojecting X/Y coordinates to mean reference point)

• merge set1=ev1.fits set2=ev2.fits outset=evout.fits withradec=Y ra=1.1 dec=-0.7 (Merging two event files, reprojecting X/Y coordinates to user reference point)

• merge set1=ev1.fits set2=ev2.fits outset=evout.fits withset1adjustpos=Y set1deltara=0.012 set1deltadec=-0.003 set1deltaposangle=0.001 (Merging two event files, reprojecting X/Y coordinates to mean reference point - set1's events are corrected for small attitude corrections prior to merging)

• merge set1=att1.fits set2=att2.fits outset=attout.fits (Merging two attitude files, i.e. atthkgen output files)

• merge set1=orb1.fits set2=orb2.fits outset=orbout.fits Merging two orbit files, i.e. orbit output files)

Note: it is possible in many cases to treat the output files as ordinary (non-merged) files. For example, creation of an exposure map is possible for merged data: First merge the relevant event files and associated atthkgen output files, then form a sky image (via evselect) from the merged event file, then run eexpmap as normal using this image and the merged event and attitude files.

Just to reiterate, do take care with any merged output.
