Slope profiles of individual redMaPPer clusters. The profiles of three clusters are highlighted in this figure to demonstrate the trends of individual clusters. While the CG slope rapidly steepens (more negative) at larger radius within the first 30 kpc, the profiles become very noisy afterwards. It is much more difficult to identify the dip in the individual profile measurements.
