Fig. A.1


Logarithmically scaled XMM-Newton EPIC low background images integrated in 2′′  ×  2′′ pixels of the M 31 observations combining PN and MOS 1 and MOS 2 cameras in the (0.2–4.5) keV XID band. The data are smoothed with a 2D-Gaussian of FWHM 10′′, which corresponds to the point spread function in the centre area. The images are corrected for unvignetted exposures. Contours in units of 10-6 ct s-1 pix-1 including a factor of two smoothing are at (8,16,32,64,128) in the upper left panel, at (6,8,16,32,64,128) in the upper right panel, and at (4,8,16,32,64,128) in both lower panels. Sources from the XMM LP-total catalogue are marked as 60′′  ×  60′′ squares.
