Left: location of XLSSC 102 on the scaling relation between the spherically integrated Compton parameter Y₅₀₀ and the mass proxy M_YX, 500. The legend is the same as in Fig. 11. Masses are estimated via the Y_X profile and the Y_X, 500 − M_YX, 500 from A10. As explained in Planck XX, the scaling relations between Y₅₀₀ and M_HSE, 500 or M_YX, 500 are the same and only the uncertainties and intrinsic scatter change. Right: ratio of the spherically integrated Compton parameter Y_SZ to its X-ray analogue Y_X, computed using the X-ray peak. Here Y_X is computed using the temperature estimated from the combination of SZ and X-ray data. The solid black line shows the calibration from A10 and the dotted line indicates the value for an isothermal cluster. The dashed black line marks 0.6 Mpc, which is close to the r₅₀₀ values found in Sect. 5.1.
