Notes.

^(a)

The listed values are those from Whitmore et al. (2010) and that fitted from Brγ EW (see text).

^(b)

Size (FWHM) measured from continuum emission at 345 GHz.

^(c)

Error bar only includes the error on the cloud mass.

^(d)

Column density at the center of the GMC, computed as N_H = M_H/Area.
