Notes.

(a)

Name of the closest H II region as identified by Henize (1956).

(b)

CO luminosity of the closest CO(1−0) cloud in the MAGMA physical decomposition catalogue. LCO is derived using the CPROPS method. The hosting cloud ID number in the catalogue is indicated in parenthesis.

(c)

CO luminosity of the associated CO(2−1) cloud taken as part of the COSSA project (PI: van Kempen, priv. comm.). The extraction is also performed with CPROPS.

(d)

The rms is estimated from the HCO+(2−1) spectra (in Tmb) with 2 km s−1 channel width.

(e)

The various line characteristics are derived via a Gaussian fit to the line. Values are provided for 3-σ detections.

(f)

We use a systemic velocity vsys = 262.2 km s−1 for the LMC and 158 km s−1 for the SMC.

(g)

Upper limits are estimated from the rms and assuming a linewidth of 5 km s−1.
