Component spectra (blue, red, orange) and resulting summed spectrum (black) for A in the top panels, and the four component spectra (blue, red, orange, cyan) and resulting summed spectrum (black) for B in the bottom panels, in the regions of the La II, Ba II and Eu II spectral lines respectively. The C09 IDs for each set of spectra and the resulting mean stellar parameters (T_eff, log g, [Fe/H]) and S/N for the final summed spectrum for each of A and B are given.
