\caption[] {\label{tab:stdphot}
Photometric data for the eclipsing binaries and the comparison stars
in the $uvby$ and $\beta$ standard systems.
For the eclipsing binaries, the ${uvby}$ information is given at maximum light level outside
eclipses. 
The $\beta$ information is the mean values outside eclipses.
%see also Fig~\ref{fig:beta}.
$N$ is the total number of observations used to form the mean values, and
%$\sigma$ is the r.m.s. error (per observation) in  mmag.
$\sigma$ is the rms error (per observation) in  mmag.
