Scaling relation between the SZ flux and the cluster mass. The blue points are those obtained in this work, at redshift z ∼ 1 and M₅₀₀ ∼ 2 × 10¹⁴ M_⊙. The black points correspond to the Planck calibration sample from Planck Collaboration XX (2014), at a mean redshift of z = 0.19. The gray band provides the best-fit relation and the intrinsic scatter. Other individual measurements obtained with NIKA and NIKA2 are reported as indicated in the legend. We note that the systematic uncertainty associated with the center definition and pressure substructure reported in Paper XLIV is comparable to the size of the error bars for XLSSC 102. Left: masses obtained from Y_X − M relation. Right: masses obtained from HSE assumption (NFW mass modeling).
