Notes. The columns show the radial bin, the number of GCs in the bin (NGC), the positions of the blue and red peaks (μb and μr), the sigma of the two Gaussians (σb and σr), the position of the separation between the blue and red populations (μmed), the Bootstrap (DD) parameter (Boot (DD)), and the fraction of blue clusters (fblue).
