Scientific paper

Eight open clusters have been observed with uvbyß photometry and for seven of them the metal abundances have been determined. Six of these have similar metallicities. They are close in space and are also known to have similar ages and radial velocities. These clusters are suspected of having a common origin. Some studies are made of the reliability of the photometric system. A large gain in limiting magnitude can be achieved against an unimportant loss of accuracy if interference filters are removed.
