Abstract:
We present 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, 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 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)
