One and two dimensional likelihood distributions for the Metropolis-Hasting estimates of the non-LTE condition toward the SW component of the 2009 and 2011 campaign. Only a subset of the parameters is represented. The blue dashed lines correspond to the common range of temperatures for which collisional rates are available in the LAMDA database for the considered set of species. The normalized 1D likelihood distributions (last row) are fitted by a Gaussian distribution (red continuous line).
