j₁ = 1 selection of WST coefficients on a logarithmic scale for the data set presented in a lexicographical order on (j₁, θ₁, j₂, θ₂). This specific selection of coefficients is arbitrary, and we find similar results for other scales and the other data sets. Vertical dashed and dotted lines delimit distinct θ₁ and j₂ values, respectively. Top panel: original data (solid lines) and the RWST fit (dotted lines) corresponding to the model of Eq. (24), while bottom panel: normalized residuals of the fit.
