Fig. 7.

Integrated Compton parameter $Y_{SZ}^{0' . 75}$ $Y^{0{\prime}.75}_{SZ}$ computed from our fit to individual clusters (median with 68% uncertainty) vs. values from Bleem et al. (2015, mean with 1σ error). Despite the strongly constrained shape that they assumed for their estimation method, there is a clear trend between the two estimates, although with an offset.
