Examples of the observed (black dots) and best-fitted synthetic spectra in the vicinity of the 614.17 nm Ba II line (red lines) in the GIRAFFE spectra of the target stars characterised by different effective temperatures (Teff ≈ 4250 K, top panel; Teff ≈ 4750 K, bottom panel). The continuum level is shown as the gray dashed line.
