Datatype: uvbym

This datatype collects the average values computed at our Institute of Astronomy for the Strömgren uvby system. These data are only a selection of stars in open clusters from the complete catalogue produced by B. Hauck and M. Mermilliod (CDS II/158A).

Again the mean ß data are collected separately in the database. The corresponding datatype is beta mean.
