# Table 1 Defnition of the different parameters and their priors and posteriors based on current literature [8,9,10,11] (see also Fig. A1). For priors, some upper bound and/or lower bound have been imposed by the observations. U is for uniform distribution and tN for truncated normal distribution (tN [mean,std.,limit inf,limit sup])
