This table contains a catalog of 8205 known or suspected Ap, HgMn and Am stars. This is a major update of the authors' first edition of their catalog of Ap and Am stars, and includes revised identifications, additional stars, and revised information obtained m the literature. This table was created by the HEASARC in July 2009 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/III/260">CDS Catalog III/260</a> file catalog.dat. It replaced an earlier version based on the 1st edition of the Ap and Am Stars Catalog (Renson et al. 1991). This is a service provided by NASA HEASARC .
