Spectral view of APOGEE spectra for the 326 candidate VMP stars in this work (grey lines), after cleaning the sample. Vertical thin lines across the wavelength space connect to artefacts in some of these spectra that are not affecting the overall analysis. Also shown are the averaged APOGEE spectra for red giants with temperatures and gravities in a range comparable to that of the bulk of our sample (4100 K < T_eff < 5200 K and 0.5 < log(g) < 3.5) and a distinct range in metallicities. The comparison clearly shows that our selected sample stars are indeed very metal poor.
