General Catalogue of Ap and Am stars

This is a major update of the catalogue of Ap and Am stars (Renson et al., 1991, III/162). It includes revised identifications, additional stars and revised information.

Bertaud and GC identifications were suppressed. HIP and TYC identifications were added. The GC number can be found in notes N for stars without HIP number and for double stars when the components have different numbers (the GC of the other component is then given in note D).
