Comparison between XMM-Newton EPIC-pn and pn+MOS latitudinal profiles. Average count rate per pixel over Galactic latitude (b), extracted from a profile of 0.5 deg width centred at Sgr A^*. With red dots we show the profile extracted from the EPIC-pn mosaic, while with black dots we show the profile extracted from the pn+MOS mosaic, after scaling the MOS exposure maps to account for the effective area differences between MOS and pn at the 6.62-6.8 keV band.
