\caption{Absolute Abundances of NGC~3293, NGC~4755, NGC~2004 and NGC~330
stars. The abundances presented below are the mean absolute abundances of each species
studied, using the initial atmospheric parameters from Tables~\ref{galpar} and~\ref{mcpar}. Numbers in the parentheses represent the number of lines of each species
observed in the star, only 1~line was considered for C~{\sc ii}, Mg~{\sc ii} and Si~{\sc iv}, 2~lines for Si~{\sc ii} and 3 for Si~{\sc iii}. Uncertainties on the
abundances account for both random and systematic errors as discussed in Sect.~\ref{aberror}. Abundances are presented as [X]~= 12~+ $\log$~([X/H]) in units of dex.}\label{ablin}
