Survey footprints displayed on top of the Planck-Herschel-Extinction dust column-density map (Lombardi et al. 2014). The grayscale shows the line of sight extinction, given in A_{K, Herschel} (mag). The contours show the survey coverages for VISTA (blue), Spitzer/IRAC1 (green), Spitzer/MIPS1 (red), and Herschel (orange). The small green boxes are control fields for the Spitzer/IRAC bands, which are partially overlapping with VISTA. The red and orange circles, located at the position of the ONC, result from saturated MIPS1 and Herschel photometry respectively. Indicated are the two main regions in Orion A, the Lynds dark cloud L1641 (including L1647), and the ONC region. The B-star κ-Ori and the O-star σ-Ori are marked for orientation. See also Fig. 1 in Paper I for an overview of some sub-regions.
