A photometric method for selecting AP stars The paper describes a photometric method which is independent ofluminosity and interstellar reddening, developed for the selection of Apstars with spectral type earlier than A5, excluding Hg stars. Thismethod was applied to the star clusters measured by the photometricsystem of Geneva Observatory.
