However, it may be considered as an evidence of a slight (0.3 dex) Oxygen overabundance in metal POOl' stars. 3.6 m Telescope References October 1984: Hunger/Heber/Drilling/Kudritzki, Alioin/D'Odorico/ Pelat, Dravins/Linde/Nordlund/FredgalGahm/Ay Clegg, R.E.S., Lambert, D.L., and Tomkin, J., 1981: Astrophysical res/Linsky/Simon, Eriksson/Saxner, Gratton/Orto Journal 250, 262. lani, Maurice/Lequeux/M.
