New Coralie RV data for ℓ Car (N = 324). The large panel shows the phased RV curve, distinguishing data from different epochs by symbol style and color. The two right-hand panels provide close-ups around maximum (upper) and minimum RV (lower), and show the median RV uncertainty as an errorbar (too small to discern in this case). The bottom panel shows residuals around an “average” Fourier series model fit to the combined data set (fit procedure described in Anderson et al. 2013). Figures for the other Cepheids are provided in Appendix A.
