T_max comparison for S/N simulations. Top panel: difference in T_max between the S/N simulations (Sect. 5.2) and reference sample (ΔT_max). The weighted average ΔT_max is −0.007 days (vertical dotted line). Bottom panel: ΔT_max over the uncertainty in T_max (i.e. significance) for the S/N simulations. The average significance is 0.23 (vertical dotted line), while very few simulations have a significance greater than 3.0. The average uncertainty in T_max (0.12 days) is larger than the weighted average ΔT_max.
