\footnotesize
\begin{itemize}
\item [Note 1]: $\Delta$S values from previous work have been transformed 
to [Fe/H] using equation (1). As discussed in the text the uncertainty in the 
[Fe/H] values, both in this work and in previous work, is typically $\pm$0.13 dex.
\item [Note 2]: only one observation of this star was made; hence the larger errors.  Based on 
the large amplitude shown in the GCVS it is assumed to be an  'ab' type.
\item [Note 3]: see Section 5 for a discussion of this star for which the classification as an RR Lyrae is uncertain.
