Notes. The columns show the magnitude bin (g′0), the number of sources 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 separation of the peaks (Bootstrap (DD), defined as the separation of the means relative to their widths), and the number of components defined by the Akaike Information Criterion (N).
