Monte Carlo realizations of the fraction of the stellar mass of the CG galaxy residing in the population of bound star clusters. The uncertainties on the normalization of the SCMF and the stellar mass of the host galaxy are included (see the text for details). From left to right, the SCMF is evaluated for slopes β of −1.5, −2.0, and −2.5 by adopting three different low-mass limits, as indicated in the legend of each panel. Calculations have been performed assuming the fiducial magnification values (while the behavior with varying magnification is shown in Fig. A.1). The vertical line bar marks the case where the total stellar mass of the star clusters equals that of the host galaxy (fraction equal to 100%).
