Here, only the final images are kept and have the prefix ``M31_''. EPIC-pn and MOS exposures are not weighted. The images are smoothed adaptively, using one smoothing template for all energy bands. The template is calculated to have a desired signal to noise ratio of 6.0 for the combination of the energy bands 0, 2, and 3. The images are masked to ensure a total (pn + MOS1 + MOS2) exposure above 2000 sec.
