Upper left panel: surface density of GC candidates in NGC 3115, corrected for background contamination, vs. galaxy semimajor axis length, SMA. The binned data are shown with gray circles, the r^1∕4 law is fit with a solid line. The green long-dashed line denotes the g-band light profile from Spavone et al. (in prep.), arbitrarily scaled vertically to match the red GC density profile. Lower left panel: as upper, but separately for blue GCs (blue triangles and dashed line) and red GCs (red squares and dotted line). Right panels: as left, but for the GCs in NGC 1399.
