Distribution of the differences between the input parameters and the fitted parameters without noise filtering (red) and with the wavelet-based noise filtering (blue) for b² and ω, the fitting parameters of the software package FITSH. These are in principle the same as the bottom row of Fig. A.4 of Kálmán et al. (2023), with the uncertainty of the fitting parameter (b′) used for the calculation of the blue histograms. The medians, variances, skewnesses, and kurtoses of the distributions are also shown.
