Notes. The results are grouped into sets of columns for single-, double-, and triple-matched Planck objects. For each grouping, the total number of Planck sources is given in parentheses in the heading. The table entries list the number of matches in matrix format, such that the element (i,j) of the matrix gives the number of Planck sources with both i- and j-ranked redMaPPer counterparts. For example, six of the 438 triple matches have a good second-ranked counterpart only, while eight have both good first- and second-ranked counterparts.
