Difference in the ν_max values extracted from the fits using a two super-Lorentzian and a four super-Lorentzian granulation model. Left and middle panels: difference in ν_{max, fit} for the RG-binary light curves where both components (Star A and Star B) are pulsating. Right panel: difference in ν_{max, fit} for the RG-binary light curves where only one component (Star A) is pulsating. The axes, symbols, error bars and colour-coding is the same as in Fig. 5, except that the horizontal axis corresponds to the absolute percentage difference between the ν_{max, fit} values for the two super-Lorentzian (2SL) and four super-Lorentzian (4SL) cases.
