Radial velocities (RVs) of components Ac1 (orange) and Ac2 (green). The observed values derived from the spectra (Mayer et al. 2022; error bars), synthetic values directly derived from our N-body model (dots), and residuals (red) are plotted. Large residuals are present close to the eclipses (phases 0.0, 0.5) because the individual lines (RVs) cannot be reliably separated, also for the component Ac2, which has very broad lines (hence uncertain RVs).
