Notes. (a) Masses are calculated mainly from the SCUBA 850 μm fluxes by Di Francesco et al. (2008). (b) Based on 1.2 mm continuum data from Beuther et al. (2002). (c)Based on 1.1 mm continuum data from Ginsburg et al. (2013). (d)Based on C18 O(3–2) data from Maud et al. (2015); effective radii for G100 ~0.34 pc and for G108 ~1.4 pc. (e) Associated features (a.f.), a: cm continuum; b: H2O maser; c: CH3OH maser.
