Comparison of the input granulation signal with those from the maximum-likelihood values of the two and four super-Lorentzian granulation model fits, for one of our binary-RG PSDs where both components are pulsating. The super-Lorentzians used as inputs are represented by the solid red curves, with the two and four super-Lorentzians fits represented by the dark blue and blue-green dash-dotted lines respectively.
