\caption{\label{finalfilestable}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.}
