Marginalised posterior distributions of the 24 cluster masses obtained from the joint fits of UPP and M_500, i parameters to data pressure profiles. We follow the same colour scheme as in Fig. D.1. In grey, we indicate the prior distribution considered for each parameter, corresponding to Gaussian distributions centred on the dynamical mass estimates from Sereno et al. (2025) with dynamical mass measurement errors as their standard deviations. All masses are in 10¹⁴ M_⊙ units.
