Top panel: column density map with contours at 3 × 10²¹ cm⁻² and 10²² cm⁻². Bottom panel: dust temperature map. In both panels, the magenta line in the bottom-left corner shows the angular scale corresponding to 1 pc at 300 pc; J2000.0 coordinates grid is shown. Both maps have a spatial resolution of 36′′. 1. The anticorrelation between N(H₂) and T_d is evident: regions at high/low column density are cold/warm, with few exceptions in IC348 and NGC 1333.
