Fig. 1
De-projected Herschel FIR emission map (upper panel) and GALEX NUV emission map (lower panel) of M 31, overlaid with the studied segments. Segments 3, 7 and 8 (blue curves) were defined on the basis of the NUV emission map, the other segments (red curves) from the FIR map. Emission along the segments was integrated, yielding the mean cross section (profiles) of each segment. The width of the cross sections (marked with green line for segment 9) is 3 kpc for all segments.
