Table 2: Summary of the cleaned and filtered observations used in the production of the EPIC background files, separated into the different combinations of instrument, instrument mode and filter used. LIVETIME is the livetime keyword value for the central CCD i.e. corrected for periods of high-background and dead-time. For the PN full-frame mode with the medium or thin filter, the files have been split between the two hemispheres based on the galactic centre and galactic anti-centre individual event pointings.
