Atomic gas depletion time, τ_HI, plotted against M_star in the left panel, and against sSFR in the right (both in logarithmic units). The best-fit power-law regressions are shown by short-dashed gray lines in both panels, and the MAGMA medians by a heavy curve; the gray regions correspond to ±1σ of the data. The heavy red long-dashed curves give the xCOLDGASS medians (Saintonge et al. 2017). As in Fig. 1, galaxies are colored by gas fraction.
