Mass comparison examples. From left to right, we compare the mass estimates of PSZ2 to AXES-2MRS, ACT-DR5 to CODEX, and ACT-DR5 to MCXC. The points with error bars show all clusters in common between each pair of catalogues, regardless of whether they are part of CHANCES. Thin blue lines show y = x, and the thick orange lines show the maximum-likelihood estimates given in the legends. The extremely small uncertainties in PSZ2 and AXES-2MRS only consider statistical uncertainties. We account for this fact by including an intrinsic scatter term in the fits. These fits correspond to the adopted normalisations discussed in Sect. 3 and listed in Tables 1 and 2.
