The calibration process of long baseline stellar interferometers requires theuse of reference stars with accurately determined angular diameters. We presenta catalog of 374 carefully chosen stars among the all-sky network of infraredsources provided by Cohen et al. 1999. The catalog benefits from a very goodsky coverage and a median formal error on the angular diameters of only 1.2%.Besides, its groups together in a homogeneous handy set stellar coordinates,uniform and limb-darkened angular diameters, photometric measurements, andother parameters relevant to optical interferometry. In this paper, we describethe selection criteria applied to qualify stars as reference sources. Then, wediscuss the catalog's statistical properties such as the sky coverage or thedistributions of magnitudes and angular diameters. We study the number ofavailable reference stars as a function of the baseline and the precisionneeded on the visibility measurements. Finally, we compare the angulardiameters predicted in Cohen et al. 1999 with existing determinations in theliterature, and find a very good agreement.Comment: Conference "Interferometry for Optical Astronomy II", SPIE 200
