The observed spectra (black curve) of the Galaxy EID 85949 is compared to two theoretical stellar spectra computed with the same T_eff  and log g  (4000 K and 1.00, respectively), but having a different metallicity. The blue line spectrum has a Solar-like metallicity, while the red one is depleted by −2.5 dex. Both spectra are shifted by RV = 7810km s^-1 (z = 0.026) to match the observations.
