Probability distribution of signal peak (top) and centroid (bottom) location with respect to reference center in three wavelengths, for XLSSC 072, XLSSC 100, and XLSSC 102, from left to right. The BCG coordinates are indicated by the black stars. Contours give the 68% and 95% confidence interval. We note that we recover a posterior distribution that is in good agreement with that reported in Paper XLIV for XLSSC 102.
