table only includes
estimates that are based on observed emission lines.
Columns 1-4 specify the source reference, the wavelength range
(O - optical, and U - UV), the stellar effective
and the mean electron temperature (
used in the study. Columns 5-9 give element abundances using
the same units as in Table 2. In
Cols. 10-12 we also give abundance ratios relative to oxygen.
Uncertainties are, were provided, given in parentheses.
A colon indicates an uncertain value of our best-match model.
The abundances of our best-match model are given in the row marked this
work. In the last two rows we, for comparison, give the mean
abundance distribution of the Galactic disk (
and the halo-PN BoBn-1 (the values of this object are taken from Howard et al. 1997).
