Notes. The number of spaxels considered for the statistics for each region is done. Sign. stands for the significance level of the null hypothesis in the Lilliefors test. If the null hypothesis cannot be rejected with more than 10% confidence, then the Gaussian fit is assumed and the corresponding mean and dispersion values are taken (in bold font). Otherwise, the mean and dispersion are those of the distribution not fitted.
