Distribution of the offsets of the fitted MBProj2D X-ray centroid and the optical eROMaPPer BCG coordinates, split by cluster class. The distribution for the 5721 filtered extent-selected clusters is shown in black, normalized for better visibility. The median offsets are indicated by the dashed lines. Compared to the median offset of ~86 kpc found for the filtered extent-selected sample, the offsets are generally higher for Class 2, Class 3, and Class 5 and are much lower than for Class 4. While large offsets can hint at mergers for extent-selected clusters, for the point source sample, they are more likely to indicate a chance projection of the cluster and the real point source along the line of sight.
