Top and middle panels: alignment between the BCG (top panel) or ICL (middle panel) with the cluster galaxies’ orientation. The data from Huang et al. (2016; red) and West et al. (2017; blue and black) are renormalized and overplotted for comparison. Bottom panel: direction of the ICL offset compared to the direction of the cluster galaxies’ offset with respect to the BCG. A value of 0° means that the ICL and the cluster galaxies (on average) are offset in the same direction.
