Notes. This table is available in its entirety at the CDS. OGLE510/HV879 is common to both samples and is considered here only once, namely in Table 7.

^(a)

Logarithmic abundance with respect to hydrogen, in solar units: [O/H] ≡ A(O)_star − A(O)_⊙, where A(O) = log(N_O/N_H)+12 and we adopt A(O)_⊙ = 8.69 from Asplund et al. (2009).

^(b)

Uncertainty in the abundance determination according to Cayrel et al. (2004), which includes the effects of covariance among the stellar parameters.

^(c)

No oxygen abundance is reported, either because the EW of the lines could not be measured, or because convergence was not reached in deriving the abundance (3 out of 21 stars).
