\caption {{\it EW}s  of the 6300.30~\AA~O~{\sc i}~line  derived oxygen abundances. In
both columns, the  global cluster errors for  the cluster  refer to the
standard deviations in the abundances originating in the single stars,
while reported errors in single  star abundance measurements come from
the  uncertainty in the {\it EW}s.  See the text for  the  errors due to the
parameter uncertainty.
