The fits to the Ca II infrared triplet for the five CEMP stars. The black line with the gray shaded region gives the observed normalized flux and the corresponding uncertainty. The blue dashed lines are the best-fit synthetic spectra. As the fit is highly sensitive to the continuum normalization, we fit the model continuum to best match the observed spectra. The red dashed line gives the continuum normalization for the best-fit model.
