Spearman correlation coefficients between subhalo abundance and concentration (circles), half-mass scale factor (triangles), and the sub-to-host halo mass ratio of the largest subhalo (stars) for hosts in each Symphony suite. The unfilled circles indicate that we show the absolute value of the anticorrelation with host concentration; the other correlation coefficients are positive. Error bars indicate 1σ jackknife uncertainties. Note that the horizontal error bars are smaller than the markers, and that the three error bars for each suite are offset horizontally for visual clarity. Subhalo abundance is measured above our conservative sub-to-host halo convergence limit of M _sub/M _host > 2.7 × 10⁻⁴ for all suites.
