Notes. From left to right, the columns provide a brief description of each parameter, its reference name as used in this work, the assumed prior range, and the best-fit values with their credibility intervals for two different models. Model 1, differently from Model 2, includes a very broad and, if associated with the Hβ, very redshifted Gaussian component. Priors are assumed to be either uniform or log-uniform for each parameter. The last row reports the evidence of the two models.
