The VLTI calibrators program: the objective is to provide a catalogue with a sufficient number of sources having a known angular diameter, either from direct measurements from the VLTI or other interferometers or from indirect estimates. The compiled data base can be used to calibrate the instrumental visibility factor both in the near-IR and the mid-IR ranges (AMBER and MIDI). (Richichi and Percheron, 2001).
An electronic version of the catalogue is available at http://www.eso.org/~arichich/download/charm/..
