VELOCE data and fit to XX Car, which exhibits a double-bumped descending RV branch. Only Coralie14 observations were used in this Fourier series fit employing 13 harmonics. The two peaks are clearly sampled. The data quality is sufficient to show the shortcoming of the Fourier series fit in reproducing the two bumps whose slopes are slightly less steep than implied by the fit to the overall RV curve.
