Notes. 

(a)

Calculated from Trot(NH3) from Krause (2003) and SSK08. Krause (2003) reported a slightly higher Tkin value of 11.8 K for J18364 SMM1.

(b)

For G015.05 MM1, Tdust is from Rathborne et al. (2010). For I18223 MM3, the two Tdust values, 15 and 18 K, are from Beuther & Steinacker (2007) and Beuther et al. (2010), respectively. The Tdust value for J18364 SMM1 is from Birkmann et al. (2006).

(c)

For those sources whose name start with “IRDC”, Sν refers to MAMBO 1.2-mm flux density from Beuther et al. (2002a). For G015.05 MM1 and G015.31 MM3, the quoted value is the MAMBO-II 1.2-mm flux density (Rathborne et al. 2006). In the case of J18364 SMM1, we give the SCUBA 850-μm flux density from Birkmann et al. (2006).
