M₅₀₀ estimated from the joint detection for the 1060 ComPRASS candidates matching a confirmed SZ cluster vs. the published M₅₀₀ of the corresponding cluster. The dotted red line indicates the line of zero intercept and unity slope. The solid blue line indicates the median ratio. The dashed blue lines indicate the interval of ±2.5σ around the median ratio. Outliers are highlighted with a blue (high estimated mass) or red (low estimated mass) square; see text. Green crosses indicate SPT clusters that are not in Planck. Cyan crosses indicate ACT clusters that are not in Planck. The inset panel shows the histogram of the logarithm of the ratio between the estimated and the published M₅₀₀.
