Planck Y₅₀₀−M₅₀₀ scaling relation (black line; Planck Collaboration XX 2014) together with the 71 points (red squares) used for its calibration from the study of low-redshift clusters (z < 0.45). The two estimates of Y₅₀₀ based on the joint tSZ analysis with and without masking the over-pressure region in PSZ2 G144.83+25.11 are shown with the blue and the green points, respectively. All the masses are estimated using the Y_X mass proxy.
