Abstract
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.


Key words: techniques: high angular resolution -- techniques: interferometric -- catalogs -- occultations -- stars: binaries: general -- stars: fundamental parameters

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
