Notes. Npix denotes the number of reliable pixels used for the analysis and σrel the median relative uncertainty for this sample. The mean value of the relative parameters are given in the upper part of the table, along with the standard deviation on their distribution. The sum of the additive parameters are given in the bottom part of the table, along with their uncertainty.
