The abundance of oxygen was determined for selected very metal-poor G-K stars (six giants and one turn-off star) based on the high S/N and high-resolution spectra observed with the Keck HIRES in the red through near-IR region comprising the permitted O i lines (7771-5, 8446) along with the [O i] forbidden line at 6363 Å. It turned out that both the abundances from the permitted line features, O i...
