Parameters	H₂ source	H ii source

Size	05	04
e_c	~20	−
n_e [cm^-3]	−	58^a
Mass [M_⊙]	1.3 × 10⁷^b	4.8 × 10⁴^c
N_ion [phot. s^-1]	<2.6 × 10⁴⁹^d	8.5 × 10⁵⁰^e

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.
