For three models of one solar mass and solar metallicity, the results of Δν versus ν_max (left) and α versus Δν (right) for 5000 perturbations of 5% uncertainty in ν_max and the individual frequencies. The different colours indicate different sets of modes (see legend where the n value of the lowest frequency mode of the set is indicated) that are selected to be the ones closest to the perturbed ν_max value. The vertical gray dashed line indicates the nominal value of ν_max of the respective model. Histograms of the parameters are shown in the top and right panels, respectively, with the same colour code as the main panels.
