Methode photometrique de selection des etoiles Ap.
Abstract
The paper describes a photometric method which is independent of luminosity and interstellar reddening, developed for the selection of Ap stars with spectral type earlier than A5, excluding Hg stars. This method was applied to the star clusters measured by the photometric system of Geneva Observatory.
