Examples of spectral lines from a FLAMES spectrum in three different setups. Top: the HR8 setup includes Sc II (503.1 nm), Fe I (505. nm), Y II (508.7 nm), and Ti I lines (512.2 nm), as well as the La II line at 511.4 nm, all marked with colored, shaded regions. Central: for the HR11 filter, we display the following lines: Co I (564.7 mn), Na I (568.2 nm), Si I (569.04 nm), Cu I (570.02 nm), Ca I (570.1 nm), one line of the Mg I b Triplet region (571.1 nm), V I (570.1 nm), Ni I (574.8 nm), and Cr I (578.1 nm). Bottom: for the HR15 setup, the colored areas highlight the Ba line (649.6 nm) plus an adjacent Fe line (649.6 nm).
