XMM-Newton EPIC 'Blank Sky' Count Rates

The following graphs show average count rates for each set of observations for each 'blank sky' file, based on the instrument-filter-mode classification in the standard SSC energy bands (0.2-0.5keV, 0.5-1.0keV, 1.0-2.0keV, 2.0-4.5keV & 4.5-12.0keV) and for pattern==0 or pattern<=12 for MOS or pattern<=4 for pn. In and out field of view (FOV) count rates are given. The in-FOV count rates were taken from a circle, radius 12000 (10 arcmin) in DETX, DETY units centered at DETX=0, DETY=0. The large spread in the observed count rates is indicated by the error bars which are one standard deviation on the mean.
