Description:
We present a detailed and uniform study of oxygen abundance from two
different oxygen lines at 6158Å and 6300Å in a large sample of
solar-type stars. The results are used to check the behaviour of these
spectral lines as oxygen abundance indicators and to study the
evolution of oxygen in thick and thin disk populations of the Galaxy.
Equivalent width measurements were carried out for the [OI]6158 and
[OI]6300 lines. LTE abundances were obtained from these two lines in
610 and 535 stars, respectively. Careful error analysis has been
performed.

Global Notes:
Note (G1): the populations are:
hamr = Hα metal-rich
thick = thick-disk population
thin = thin-disk population
halo = halo population
Note (G2): Upper and lower errors are calculated at the abundance values
where the probabilities are 0.159 and 0.841 for the negative and
positive errors, respectively, relative to the madian [O/H]m
