Synthetic spectra around the Si 8556 Å-line (top) and the Sr 4077 Å-line (bottom panel) in star 204 (black histograms). The blue lines have been computed with the best-fit abundances of [Si/Fe] = 0.44 and [Sr/Fe] = 0.00 dex, accounting for errors of ±0.2 dex (red). The green lines show syntheses without any Si and Sr, respectively.
