  We present in this paper a catalog of reference stars suitable for
calibrating infrared interferometric observations. In the K band, visibilities
can be calibrated with a precision of 1% on baselines up to 200 meters for the
whole sky, and up to 300 meters for some part of the sky. This work, extending
to longer baselines a previous catalog compiled by Borde et al. (2002), is
particularly well adapted to hectometric-class interferometers such as the Very
Large Telescope Interferometer (VLTI, Glindemann et al. 2003) or the CHARA
array (ten Brummelaar et al. 2003) when observing well resolved, high surface
brightness objects (K<8). We use the absolute spectro-photometric calibration
method introduced by Cohen et al. (1999) to derive the angular diameters of our
new set of 948 G8--M0 calibrator stars extracted from IRAS, 2MASS and MSX
catalogs. Angular stellar diameters range from 0.6 mas to 1.8 mas (median is
1.1 mas) with a median precision of 1.35%. For both the northern and southern
hemispheres, the closest calibrator star is always less than 10 degree away.
