Contribution of different types of objects to the total number of point sources detected in NIR and MIR at each band (S _total). AGB stars are shown as asterisks, late-type pulsating giants as X sign, multiple stellar systems as triangles, YSOs as diamonds, post-AGB as filled diamonds, background objects as squares, foreground objects as filled triangles, other as circles, sources of an unknown origin as filled squares, and sources not identified as filled circles.
