Notes. The optical depth 
and column density N are given as a(b) meaning a×10b. The beam-averaged temperatures, 
, are computed from the temperature maps (Sect. 5). The dust continuum optical depth, 
, H2 column density, N(H2), and mass, M, are calculated according to Eqs. (8), (6), and (7), respectively.
