The dust-to-gas ratio, dust-to-stellar mass ratio, molecular-to-stellar mass ratio and the molecular fraction as a function of the HI deficiency. Panels to the left show the data with symbols as in previous figures: filled circles are galaxies in the M-sample, open circles are galaxies in the S-sample. Continuous lines in each panel are best fits to linear relation between def(HI) and the variable shown on the y-axis. Panels to the right of the figure show mean values in three HI deficiency bins.
