Herschel three color composite of the CNC maps at 70   μm (blue), 160   μm (green) and 250   μm (red). The yellow “x” mark the positions of our 642 Herschel point-like sources detected in at least two bands. The solid red box delineates the Gum 31 region that will be discussed in a separate paper. The two dashed red boxes delineate two clouds that are not part of the Carina Nebula and will also be discussed in a separate paper. The green polygon marks the region of the Carina Nebula that is also covered by the Spitzer IRAC maps. The two green dashed lines within the polygon mark the borders of the region for which our Spitzer photometry was obtained. Because the field-of-views of PACS and SPIRE are shifted to each other, there are regions that are only covered by one instrument, i.e. the red region in the south-west is only part of our SPIRE maps, and the green region in the north-east is only part of our PACS maps, respectively.
