Model fits achieved for test case n00. The models are shown in the column titles. The top row shows the synthetic data with black symbols and the modelled curves with blue lines. The middle and bottom rows show the fitted red noise and the final residuals, respectively. The coloured areas show the differences between the fits of the actual model and the leftmost model (i.e. aligned, fixed angle). Red and blue correspond to positive and negative discrepancy, respectively, and the regions with no difference are coded with magenta.
