Notes.  .

(a)

Calculated as the ratio of the integrated flux to the peak intensity.

(b)

All size scales, luminosities and masses assume distances to the LMC D = 50 kpc and SMC D = 60 kpc.

(c)

The CO luminosity is in units of 103Kkms-1pc2.

(d)

Calculated in the high-density, high-temperature limit; see text.

(e)

“Virial” molecular mass calculated from the CO luminosity as MVT(CO) = .

(f)

Go calculated from the estimated Lyman continuum luminosity and a mean distance from the ionising source to the cloud derived from the projected extent of the emission; LLyc derived from either Hα measurements (ref) or 843 MHz radio observations (ref) with an assumed black-body effective temperature of TBB = 50   000 K.

(g)

Go estimated from the far-infrared surface brightness, using Go = IIR/1.3 × 10-4erg   cm-2   s-1   sr-1
