Table 4.

Mean values of the gas fraction, fgas = Mtot gas/(Mstar + Mtot gas), and the molecular-to-atomic gas mass ratio, within r25, expressed in logarithm as a function of the morphological stage from T = 1 to T = 10, and assuming a constant XCO (Bolatto et al. 2013) and a metallicity-dependent XCO (Amorín et al. 2016).

Notes. Mean values of various ratios of all (T = 1–10) galaxies are also collected (last line). The numbers between brackets are the numbers of galaxies taken into account in the computation of mean values.
