Portion of the spectra of the star CES0048–1041 around a selection of studied lines: Ba II at 5853.67 Å, La II at 4086.71 Å, Ce II at 4165.60 Å, Pr II at 5259.73 Å, Nd II at 5255.51 Å, Sm II at 4704.40 Å, and Eu II at 4129.72 Å. The black dots represent the observed spectra. The red solid lines represent the best fit, with the respective A(X) shown in the label on the lower right corner of each panel. The red shaded areas show ±0.1 dex interval around the best fit. The blue dashed lines show synthetic spectra without the studied element.
