Comparison between modeling with ALMA+ACA (blue) and ALMA+ACA+ACT (orange) observations. The full posterior distributions of all runs can be found in the supplementary material. Here we highlight four marginalized posterior distributions to show the effect ACT observations have on the P₀ − r_s, r_s − β, Dec–M_500, c, and the M_500, c − e relationships, shown from left to right, top to bottom. The weighted median values of the ALMA+ACA+ACT runs are highlighted with black lines. For a detailed description of the effect the ACT observations have on the sampled posterior distribution, we refer to the text in Section 5.2.
