*Columns: (1) Name. (2) Total H2 mass from 12CO assuming the X-factor. (3) Total H2 mass from 13CO assuming the LTE. (4) Total H2 mass from C18O assuming the LTE. (5) The total stellar mass derived by assuming the IMF from the earliest spectral type star(s), referring to Binder and Povich (2018). The masses of O-type star(s) are adopted from the observational stellar parameters of tables 4 and 5 in Martins et al. (2005). (6) SFE derived by the total H2 mass from 12CO. (7) SFE derived by the total H2 mass from 13CO. (8) SFE derived by the total H2 mass from C18O.

†The total stellar mass of W 43 is calculated by summing up W 43 Main and W 43 South (G29.96−0.02).
