Magnitude distribution of all predicted GCs. Panel a: Distribution of apparent magnitudes of all expected GCs hosted by galaxies out to 100 Mpc. Panel b: Cumulative distribution of the relative number of GCs. The solid red line marks the VIS point source detection threshold of 26.2 and the dashed line marks 24.5 as the magnitude limit in which GCs will also be detected in NISP (see Fig. 7).
