a Same experimental spectrum as in Fig. 1c (red) superposed to the calculated EMT spectrum (black) 60 nm in radius away from the best fit. b Contrast enhanced χ2 map of EMT calculated spectra compared to the experimental spectrum of Fig. 1c with the absolute minimum identified in red and zoomed in c. These maps are differently sampled than the set used in practice to give a clear view of the overall behavior
