NFW fits to the cross-correlation data for bins 1 to 5 (from left to right, top to bottom) and the general case (bottom right). The red line corresponds to the fit to the points at the small scales only and the blue one is for large scales. The grey dashed lines show the NFW profile using the mass–concentration relationship by Mandelbaum et al. (2008) and, as explained in the text, it is not a best fit to the data; neither is the red dashed line for bin 5 (the parameter values are chosen by hand in order to produce a reasonable fit). The vertical dotted lines separate the two regimes that have been studied for each case. Grey points are considered outliers and are not taken into account for the analysis.
