Ratio of total mass in atomic hydrogen to total stellar mass for all AGES detections with known optical counterparts (pentagons) and upper limits for non-detections (grey, down-pointing arrows). The pentagons are colour coded according to their H I deficiency. The thick black line shows the median of all AGES galaxies. The orange solid line shows the median values for xGASS galaxies (Catinella et al. 2018). The grey shaded region encompasses the data excluded from the stellar-mass-limited sample. The red and blue curves and shaded regions show the median relations for AGES galaxies that are members of the A1367 cluster and non-members, respectively. [Link]
