Distances from the cluster centre for NATs and WATs, normalised by the r₅₀₀. The dashed lines show the median values of the distribution and the error bars give the 1σ statistical uncertainty on the median. The counts for each histogram are such that the area under the histogram integrates to 1. As a reference, the distribution of the galaxies in HeCS-SZ (Rines et al. 2016) is given with the grey histogram.
