Notes. From left to right, columns indicate the family F, the class, the percentage of pixels in each class relative to the total pixel sample (recalling that all the Stokes I profiles in the dataset were classified), and the mean values in the histograms of Fig. 11 for each class. For the classes clearly exhibiting two distinct populations in the histograms, three mean values are provided: one for the entire distribution and one for each population.
