This document discusses the conventions for combining region and table filters, especially with regards to the comma operator. Filter specifications consist of a series of boolean expressions, separated by commas. ... Region and table filters can be combined: foo.fits[circle(10,10,3),pi=1:5] or even: foo.fits[pha==1 (10,10,3),pi==2 (20,20,8,5)] In these cases, it is not obvious whether the command should utilize an or or and operator. ...

... The third processing stage filters the combined event list to produce the filtered event list, which contains the collection of node-specific exposure maps. ... Combining the event filtering with exposure map construction in one step assures mutual consistency. ... If the original combined event list is missing (as, for example, in the PPS) the original filtered event list is acceptable as a substitute if no changes have been made to the original attitude and housekeeping GTI. ...
