Notes. (a) Gas mass and luminosity are calculated above column density thresholds Nthres: for MM2, MM3 and C, Nthres= 5×1022 cm−2, for F1, Nthres = 4.5×1022 cm−2, for F2, Nthres = 2.2×1022 cm−2; the thresholds are chosen based on visual inspection of the N(H2) and bolometric luminosity maps (derived from integrating SED profile in a pixel-by-pixel basis) from Lin et al. (2016). (b)The system velocities (VLSR) are with reference to Urquhart et al. (2018) based on finding the identical or nearest clumps.
