\caption{{$uvby{\beta}$} indices obtained for IP~Per and
comparison stars. The pairs below the star names are the number of
points collected for each object in $uvby$ and $\beta$,
respectively. The numbers below the measures show the errors (in
mmag). The values given by Olsen (1996, private communication) are
listed in the bottom part.}
