Notes. From left to right, the columns contain the total number of detected haloes (Nhaioes), the total number of substructures (Nsubs), the mass of the largest halo (Mmax), the maximum number of substructures of a single halo (max(nsubs)), and the normalisation, index, and scatter (NX, aX, and sX as defined in Eqs. (6) and (7)) of the radii and mass comparison between each finder and ASOHF.
