Scientific paper

The mean absolute magnitude of the Ap stars (except those belonging to the Hg-Mn subgroup studied earlier) has been determined by statistical parallaxes. Results given as a function of UBV photometric indices have been checked against the absolute magnitudes derived from Ap stars in clusters and in visual binaries. The agreement is good when the errors are taken into account. It is concluded that the Ap stars do have the same absolute magnitude as the main sequence stars of the same color.
