The Catalog of High Angular Resolution Measurements (CHARM) includes most of the measurements obtained by the techniques of lunar occultations and long-baseline interferometry at visual and infrared wavelengths, which have appeared in the literature or have otherwise been made public until mid-2001. A total of 2432 measurements of 1625 sources are included, along with extensive auxiliary information. In particular, visual and infrared photometry is included for almost all the sources. This has been partly extracted from currently available catalogs, and partly obtained specifically for CHARM. The main aim is to provide a compilation of sources which could be used as calibrators or for science verification purposes by the new generation of large ground-based facilities such as the ESO Very Large Interferometer and the Keck Interferometer.
