Notes. Means have been calculated taking upper limits into account, but not lower limits. (1) Stellar mass range of the bin. (2) Number of CO-VGS galaxies in the bin. nup: Number of upper limits of CO-VGS galaxies in the bin. (3) Mean logarithm of the molecular-to-atomic gas mass ratio and its error of the CO-VGS galaxies in the bin. (4) Median logarithm of the molecular-to-atomic gas mass ratio of the CO-VGS galaxies in the bin. (5) – (7) The same for the CO-CS sample. (8) Difference of the mean logarithmic of the molecular-to-atomic gas mass ratio between CO-VGS and CO-CS (Δmean) and its error (err(Δmean)). (9) σ = Δmean/err(Δmean), only reported when there are at least four objects in each sample. (10) p-value of the Kolmogorov-Smirnov test.
