Notes. (a)Tdust, i>1 and Ni>1 [(H+)H2] are respectively the temperatures and column densities of additional greybody components. (b)These are the adopted fitting parameters for N12, in which PACS-70 μm data are excluded. When the 70 μm data are included, Tdust,
, and β become 31 ± 2 K, 4.3 ± 0.6 × 1022 cm−2, and 0.6 ± 0.1, respectively.
