Comparison of HSE and lensing mass estimates from the homogeneous samples in this work (XMM-Newton and CoMaLit) with respect to other estimates from the literature (comparison sample). Top: Relation between X-ray masses from literature and from the XMM-Newton reference pipeline without accounting for . In the left (right) the clusters with very large uncertainties and with very different XMM-Newton and CoMaLit centres are considered (not considered). Bottom: Same figure as Fig. 1, but not accounting for clusters with very large uncertainties and with very different XMM-Newton and CoMaLit centres. The dashed lines show the 1:1 relation. We give the statistical, systematic, and raw variances in units of 10²⁸ corresponding to the data points in each figure.
