Notes.

(*)

Tentative detection.

(a)

Logarithm of the cold H2 mass (in solar masses) calculated from the observed central ICO(1 − 0).

(b)

Aperture correction factor, defined as MH2,0/MH2,tot.

(c)

Logarithm of the cold H2 mass (in solar masses) extrapolated to the emission from the total disk (see text).
