Notes. Columns 1−3: rms noise, peak, average column density in 1021 cm-2. Column 4: total mass of the cloud in M⊙ above a threshold of AV = 2 mag (≈2 × 1021 cm-2, using the conversion formula N(H2)/AV = 0.94 × 1021 cm-2 mag-1Bohlin et al. 1978). A distance of 180 pc was taken for Cha I and II, and 150 pc for Cha III.
