Notes. We separate the total 1.2 mm emission into 3 different contributions: free-free, CO(2–1) and cold dust emission. Millimeter masses are computed from the cold dust emission (see Sect. 5.3). The error bar on dust masses (Mmm) is derived from the error on Sdust. It does not include any uncertainty on the dust temperatures. The last column shows the comparison between virial and millimeter masses.
