Comparison of the ν_max values of each component (Star A, left panel; and Star B, right panel) extracted from our synthetic RG-binary light curves where both components are pulsating, using a two super-Lorentzian granulation model. The vertical axis corresponds to the difference between the single-RG reference values for Star A (ν_{max, single (Star A)}) and Star B (ν_{max, single (Star B)}). The horizontal axis corresponds to the difference between the binary (ν_{max, binary}) and the single-RG (ν_{max, single}) reference values. The vertical dashed line represents the zero-point of the difference between ν_{max, binary} and ν_{max, single}. The dash-dotted green lines represent the interpolated 1 − σ level about the mean scatter of the datapoints grouped into 10 μHz bins along the vertical axis. The horizontal dashed line represents the zero-point of ν_{max, single (Star A)} − ν_{max, single (Star B)}. The error bars correspond to the 68% Bayesian credible intervals of the marginalised posterior distributions of the binary fit parameters. The symbols are colour-coded according the percentage light contribution of each component to the binary light curve.
