Left panel: density profile (logarithm of numbers per square arcmin) of all GC candidates brighter than R = 25 mag. The straight line is the arbitrarily scaled light profile of the galaxy for showing that these profiles are not distinguishable. Right panel: the density profiles for red (circles) and blue (triangles) clusters separately. The labels “blue” and “red” indicate the respective linear fits. The blue clusters show a marginally shallower profile, but the uncertainties are too large to draw conclusions.
