Notes.
Bolometric luminosities compiled from recent Herschel and Spitzer surveys with references in the final column. For the two sources in Orion, MMS6 and MMS9, some differences are found in literature. We adopt the value of 27 L⊙ for MMS6 from Manoj et al. (2013) and derive the internal luminosity of MMS9 by scaling by the ratio of the 70 μm fluxes of the two sources reported by Billot et al. (2012; see also discussion of the relation between 70 μm flux and internal luminosity in Dunham et al. 2008).
