Figure 65: The same as Figure 64 but now with δ as a function of log 10(x). This
representation is better if one wants to represent the lines x = 1 and x = y −1 :
then give the locus of the QCD phase transition.

Log10t1s Figure 66: The same as in Figure 65 but now with δ as a function of log 10(t/1 s).
We also represent the lines corresponding to the beginning (t = t−) and end
(t = t+) of the QCD phase transition.
