In the two last columns we give the average abundances and the average abundances relative to the Sun. In the calculation of the average abundances of O and Na we rejected the star #11583 because its O and Na contents deviate from the general trend (see text). For #11583 we give an upper limit for the He abundance, which is useful for the discussion, see Sect. 6. Errors for He abundance were obtained as described in Sect. 6.
