General catalogue of Ap and Am stars

A catalog of all the known Ap and Am stars, containing a total of 6684 objects, was prepared. The few stars that were wrongly considered as Ap or Am star are noted as well as some others for which their identity as Ap or Am stars is not yet well established. The catalog gives the identificators and the main observational data for each star, including the magnitude, color, spectral type, duplicity, periodicity, magnetic field, and projected rotational velocity
