Left: column density of molecular hydrogen in G202.3+2.5 as derived from SPIRE bands, assuming a modified black-body SED with fixed β = 2. Right: dust temperature in G202.3+2.5 derived from the same SED fitting. In both frames, the dark-blue solid line shows the footprint of our IRAM OTF observations, and the ellipses show the location, size (full-width at half-maximum of a Gaussian fit) and orientation of the submillimetre compact sources extracted by Montillaud et al. (2015). The regions defined in the main text are indicated with white shapes. In both frames, the inset shows a zoom to the junction region (white rectangle).
