70 μm images ([MJy/sr], left) and calculated column density ([cm^-2], middle) in logarithmic scale and dust temperature ([K], right) maps for the same clumps shown in Fig. 4, ECC G146.71+02.05 (top) and G319.35+0.87 (bottom), from Category I and II with a resolution of 36′′. Yellow and red contour levels refer to the H₂ column density thresholds 3 × 10²¹ and 10²² cm^-2, respectively. Black circles are centered at the position of the Planck clump and circle sizes correspond to the major axis given in the ECC catalog.
