Eu ii 6645 Å line in the same star B-130, shown in spectra of UVES from the present work, observed in 2011−2012, and in the GIRAFFE spectrum studied in B09. Upper panel: Eu ii 6645 Å line; lower panel: the same spectral region enlarged. The magenta dotted line represents the UVES spectrum, the blue dotted line the GIRAFFE spectrum, and the blue solid lines plot the synthetic spectra computed with [Eu/Fe] = 0, +0.3, +0.5.
