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, Cat. J/A+A/393/183), is particularly well adapted to hectometric-class interferometers. We use the absolute spectro-photometric calibration method introduced by Cohen et al. (1999AJ....117.1864C) to derive the angular diameters of our new set of stars. Description: Angular diameters for 948 G8-M0 giants (extracted from the IRAS, 2MASS and MSX catalogs) in the J, H and K bands are presented. For each star, HD and Hipparcos catalog numbers, equatorial coordinates, parallax, spectral type, photometric data (B,V,J,H,K, and 12 microns), angular diameters and three HIPPARCOS flags (about variability and binarity) are given.

Note (1): We provide only one error for all angular diameters, since the linear corrections between Uniform Disk diameters and the Limb-Darkened diameter lead to negligible corrections on the UDdiam errors. Note (2): Originally an HIPPARCOS flag. The values are the following: 1 = <0.06mag 2 = 0.06-0.6mag 3 = >0.6mag Note (3): Originally an HIPPARCOS flag. Hipparcos-defined type of variability (a blank entry signifies that the entry could not be classified as variable or constant): C = no variability detected ("constant") D = duplicity-induced variability M = possibly micro-variable (amplitude <0.03mag) P = periodic variable R = V-I colour index was revised due to variability analysis U = unsolved variable which does not fall in the other categories Note (4): Originally an HIPPARCOS flag: C = solutions for the components G = acceleration or higher order terms O = orbital solutions V = variability-induced movers (apparent motion arises from variability) X = stochastic solution (probably astrometric binaries with short period)
