Histograms of cluster size as recovered by our algorithm. Each histogram corresponds to clusters with the same size θ_c determined by the SPT collaboration. The vertical black line displays the size from the SPT collaboration increasing from 0.25 to 3 arcmin in steps of 0.25 arcmin, from left to right and from top to bottom. The red histogram shows the distribution of the size recovered by our algorithm and the thick dashed vertical blue line is the median value of our recovered values. Our recovered sizes are in good agreement with the sizes published by the SPT collaboration.
