Evolution of the temperature T for M_clust = 10¹⁵ M_⊙ and ɀ_max calculated in different ways. The lines correspond to the arithmetic mean 〈〉_a, the root-mean-square 〈〉_rms, the median of a skew-normal fitting 〈〉, and the average of a Gaussian fitting 〈〉_gauss, for which the logarithm was taken. The markers correspond to the same average processes but are performed on the logarithmic values of T.
