XMM-Newton mosaic images of M31 with 0.4–0.7 keV shown in top-left and 0.7–1.25 keV in top-right. The white dashed circles mark the fields of our northern disc LP survey, which are revealed in more detail in the zoomed images in bottom-left and bottom-right. The XMM-Newton coverage in relation to the stellar population is shown in Fig. 1 of Stiele et al. (2011). The colours are in linear scale as shown by the colour bars in each image. The units of the images are cts s⁻¹ deg⁻².
