Luminosity function for Sgr (black histogram), MW (blue histogram), M31 (green histogram), and the LMC (magenta histogram) GC systems (in the left panel). We also show separately the Sgr and LMC luminosity functions (in the right panel) as a zoomed plot of the left panel, and we use the middle panel to highlight the Sgr LF. The histograms are constructed considering a bin size of 0.5 mag.
