Fig. 1

Hypothetical model grid coverage of three observations. The resolution of the model grid is high compared to the observed uncertainties in the left panel a) and the models sample the observation well. The model grid is sparse in the middle panel b) such that the model density is not enough to resolve the 1σ uncertainties of the observations – reliable model parameters cannot be determined. In the right panel c), the models are physically unable to match the observations, i.e. the resolution of the model grid is high compared to the observed uncertainties but the models do not probe the observed region of the parameter space.
