Notes. Derived physical properties of the sample of massive clumps used to derive the o-H2 D+ detection limits described in Sect. 4.1. The sources are separated, from top to bottom, into their evolutionary classes. The error associated with N(H2) is 20% for each source. (a)The temperatures are reported on the main-beam temperature scale; (b) derived in this work. (c) Tdust, N(H2), and Class from Giannetti et al. (2017). (d) Tdust, N(H2), and Class from Urquhart et al. (2018).
