\caption{\label{t:reldata2}Data for the observed stars in NGC~2506, NGC~6134, and~IC~4651. $V$,
$B-V$ are: CCD magnitudes from Marconi et~al. (\cite{Marconi1997}) for NGC~2506; photoelectric
measurements from Clari\'a \& Mermilliod (\cite{Clari1992}) for NGC~6134; photoelectric
measurements from Eggen (\cite{Eggen1971}), Lindoff (\cite{Lindoff1972}), and Jennens \& Helfer (\cite{Jennens1975}),
as reported in the BDA, for~IC~4651. $K$ is taken from 2MASS (Cutri et~al. \cite{Cutri2003}).
Stromgren $y$, $b-y$ are: from Bruntt et~al. (\cite{Bruntt1999}) for NGC~6134, and
\mbox{Anthony-Twarog} \& Twarog (\cite{Anthony2000}) for~IC~4651. {\it S/N} has been measured at about~670~nm. Radial velocities (Col.~8, in km s$^{-1}$), are heliocentric.}
