Notes.

^(a)

Assuming ionization balance, and not correcting for extinction, scales as ;

^(b)

virial mass estimated from the intrinsic S(1) size and the CO line width;

^(c)

mass of the H ii gas uncorrected for extinction, scales as ;

^(d)

from the upper limit of the Brγ emission, uncorrected for extinction;

^(e)

derived from the Brγ luminosity, scales as e_c;

^(f)

H₂ bolometric luminosity corrected for extinction (Sect. 3.3);

^(g)

from the age and N_ion. Uncorrected for extinction, scales as e_c.
