Comparison of molecular gas masses of the 11 ALPINE FIR continuum-detected nonmerger galaxies as derived from the [C II] luminosity (Eq. (1)) and the rest-frame 850 μm luminosity (Eq. (2)). The monochromatic rest-frame 850 μm luminosity is extrapolated from the measured rest-frame 158 μm luminosity by assuming either the FIR SED template of Béthermin et al. (2017) (filled circles), or the MBB curve with β = 1.8 and T_dust = 25 K as adopted by Scoville et al. (2016, 2017) (filled stars). The open squares show the molecular gas masses derived directly from the measured rest-frame 158 μm luminosity using the calibration of Groves et al. (2015), obtained for local galaxies, between Herschel PACS 160 μm monochromatic luminosity and gas mass. The dotted line is the one-to-one relation. Overall, there is good agreement between and the different molecular gas masses estimated from the rest-frame 158 μm dust continuum luminosity, even though an average overestimate of 0.3 dex is found when considering the Béthermin et al. (2017) SED (see text for details).
