Calibration of the $Y_{\mathrm{SZ}}-M_{500}^{Y_{\mathrm{X}}}$ scaling relation. The blue dots correspond to the X-ray mass and SZ signal (with 1σ uncertainties) for each cluster in the sample. The black line shows the best-fit relation obtained in this work, with the red regions corresponding to 1σ uncertainties, the grey regions to the intrinsic scatter, and the green line to the best-fit relation obtained in Planck Collaboration XX (2014).
