H I deficiency of the Coma galaxies as a function of projected radius from the cluster centre. The individual H I deficiency measurements for the Coma galaxies are represented by the green shaded distribution for the H I detections and grey triangles for the lower limits on the H I non-detections. The average H I deficiencies for late-type Coma galaxies from Gavazzi et al. (2006) are shown in orange. The black, blue, and red triangles represent the lower limits from stacking the non-detections in annuli in three samples: all non-detections, log M_⋆ < 9.5, and log M_⋆ > 9.5, respectively. The horizontal dashed purple lines set the limit on DEF_H I values that indicate a galaxy is H I-normal.
