Radial coverage of the GC systems and ratios of stellar-to-halo mass enclosed within progressively larger radii for early-type galaxies in SLUGGS. Top panel: distributions of the median radii (R_med, GC, blue) and of the outermost radii (R_last, GC, orange) of the GC systems around the early types in SLUGGS. Both radii are normalised to the effective radius of the luminous galaxy (R_e). Bottom panel: distributions of the ratios of stellar-to-halo mass enclosed within the effective radius (R_e, green), within the median GC radius (R_med, GC, blue), and within the outermost GC radius (R_last, GC, orange). These are computed from the best-fit f(J) model of each galaxy. The dotted vertical line separates the regions where the dark matter dominates (left) and where the stars dominate (right).
