... evlist -- output event list . The output event list is a clone of the input event list in which the tables EVENTS , STDGTI0n , EXPOSU0n and REJPIXnn have been destructively filtered and the node-specific exposure maps have been deleted or replaced. The STDGTI0n tables and the REJFLAGS attribute of the EVENTS table indicate what filtering has been performed. ... The two exposure maps for a chip are not constructed unless the EXPOSU0n table for that chip is present in the input event list. ...
