Evolution of the molecular gas fraction (fgas) and the gas depletion timescale (τdep) as a function of the distance to the main sequence of star-forming galaxies (RSB = SFR/SFRMS) for the main and supplementary catalog of galaxies detected by ALMA in the GOODS-ALMA field. The solid blue line shows the relation obtained by Tacconi et al. (2018) for the median redshift and stellar mass of our sample (zmed = 2.7, M⋆, med = 8.5 × 1010 M). The uncertainty on the mean trend is obtained by Monte-Carlo simulations. In order to compare the gas fractions of all of the galaxies in our sample, we have rescaled our gas fractions according to the median redshift and the stellar mass of our sample.
