Abstract:
This catalogue contains stellar angular diameter estimate for bright
stars, complete for all stars with Hipparcos parallaxes.
The JMMC Calibrator Workgroup has long developed methods to estimate
the angular diameter of stars, and provides this expertise in the
SearchCal software (http://www.jmmc.fr/searchcal). "SearchCal" creates
a dynamical catalogue of stars suitable to calibrate Optical
Long-Baseline Interferometry (OLBI) observations from on-line queries
of CDS catalogues, according to observational parameters. In essence,
SearchCal is limited only by the completeness of the stellar
catalogues it uses, and in particular is not limited in magnitude.
SearchCal being an application centered on OLBI peculiar purposes, it
appeared useful to publish the estimated angular diameters of all
stars with known parallaxes in a static catalogue.
The present catalogue of stellar angular diameters has been obtained
from an automated SearchCal results aggregation on the whole celestial
sphere. For each star, the value of the limb-darkened angular
diameters are computed using a surface brightness method and
calibrations for (B-V), (V-R) and (V-K) color indexes.
Stars whose angular diameters estimated from the various color indexes
are not comparable, are rejected, and a reliable error on the
estimated diameter is computed (1). For details of the method see
Bonneau et al. (2006A&A...456..789B). To avoid specific confusion
problems, spectroscopic binaries in the 9th Catalogue of Spectroscopic
Binary Orbits (Pourbaix et al., 2009, Cat. B/sb9) or close visual
binaries with a separation of less than 2 arc seconds in the
Washington Visual Double Star Catalog (Mason et al., 2001, Cat. B/wds)
have been filtered out.
Description:
Limb Darkened and Uniform Angular diameters are given for 38472 stars,
extracted from the All-sky Compiled Catalogue of 2.5 million stars
(I/280, Kharchenko et al. 2009). The limb darkened diameters are
computed using the V magnitude and the (V-K) color index.
The uniform disk diameters are computed for the photometric bands (B,
V, R, I, J, H, K) using the linear limb darkened coefficients from
(Claret & Diaz-Cordoves, 1995, Cat. J/A+AS/114/247).
For each star, HD and Hipparcos catalog numbers, equatorial
coordinates, parallax, spectral type, photometric data (B,V,R,J,H,K)
and angular diameters are given.
Additionnally, the absence of a particular star in this catalogue can
also be due to a missing photometry in one of the base catalogues
or high proper motion that break catalogues cross match.
Conversely, the rejection of binaries depends on their availability as
such in the relevant catalogues.

Note (1): Magnitude flag as follows:
1 = the corresponding magnitude is a measurement
0 = the corresponding magnitude is an estimate based on the colors
deduced from the spectral type. In this case, due to the
discrete nature of the tables (SpType - color) used, a
discretization appears in the diagrams using the colors (V-I)
and (V-R)
Note (2): 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.
