Same as in Fig. 9 but for data set III. It can be seen that the components are in position (but not strength; weighting) similar to the ones in Fig. 9. The goodness-of-fit values (reduced χ²) are 8.3 for the simplistic model (2 components; second panel) compared to 3.2 for the medium complex model (3 components; third panel) and 1.8 for the more sophisticated one (4 components; final panel).
