... epframes reads a raw event list of a single CCD and exposure from an EPIC PN ODF ([ 1 ]) . ... The auxiliary, main periodic housekeeping and spacecraft time correlation files corresponding to the selected EPIC PN raw event list are needed for the computation of event time tags. epframes flags events with faulty coordinates or times in a FLAG column. ... We note that the RAWX and RAWY coordinates in the output file have values increased by +1 with respect to the raw coordinates in the ODF/SDF file. ...
