Notes. The corresponding posterior distributions are shown in Fig. C.1. As for cluster C the core-model parameters were not properly determined, we show for ne, Core its 3σ upper limit (≲99.73%) and for TCore its fit boundaries. We note that the ne parameters of both models cannot be directly compared, given the different physical assumptions of both models (see Sect. 3.3).
