Notes: (1) Sub-sample (i.e. galaxies in the field or in rich groups), (2) minimum and maximum bounds of the stellar mass bin, (3) median depletion of specific stellar angular momentum in the given mass bin with respect to the best-fit line obtained when fitting low-mass (M⋆ < 1010 M⊙) galaxies in the same sub-sample, and (4) 16th and 84th percentiles for the considered mass bin.
† Values for the field sub-sample are given as an indication but there are too few galaxies in this sub-sample for all these stellar mass ranges to derive robust constraints.
†† The depletion is evaluated as the best-fit model (with mass and redshift cuts applied) minus the galaxies’ specific stellar angular momentum. The same slope, corresponding to mass and redshift cuts applied (see Table 1), was used for both sub-samples.
