\item[$^{{\rm a}}$]
[Fe/H]$_{\rm spect}$ = [Fe/H]$_{\rm FeII}$ from SPS.
\par
\item[$^{{\rm b}}$]
Bl: no [Fe/H]$_{\rm phot}$ is calculated for Blazhko stars with
large light curve modulation;
\par
(Bl): Blazhko stars with slight light curve changes are included but
photometric [Fe/H] is less certain;
\par
* : spectroscopic [Fe/H] seems to be wrong, see the text for details;
\par
** : photometric data have larger scatter;
\par
*** : classification is uncertain;
\par
$-$ : no or poor quality light curve is available.
