Table A.1
Column names, symbols adopted to represent them, units, data types and brief descriptions of the columns provided for the catalog of the 8347 misidentified clusters. We abbreviate the counterpart assigned by NWAY as CTP for brevity. We provide variants of column names in square brackets with the variants separated by semicolons; for example, BEST_Z[;_ERR] indicates the presence of a BEST_Z and a BEST_Z_ERR column. The suffixes _ERR, _L, and _U respectively denote the symmetrical, lower, and upper 1σ errors of the quantity preceding them.
