Abstract:
This catalog 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 catalog
of stars suitable to calibrate Optical Long-Baseline Interferometry (OLBI)
observations from on-line queries of CDS catalogs, 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 catalog.
The present catalog 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. (2006). To avoid specific
confusion problems, spectroscopic binaries in the 9th Catalogue of
Spectroscopic Binary Orbits (Pourbaix et al.2009) or close visual binaries with
a separation of less than 2 arc seconds in the Washington Visual Double Star
Catalog (Mason et al. 2001+) have been filtered out.
Description:
Limb Darkened and Uniform Angular diameters are given for 38742 stars, extracted
from the All-sky Compiled Catalogue of 2.5 million stars (I/280B/ascc,
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).
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.

Note (1): Additionnally, the absence of a particular star in this catalog can also be
due to a missing photometry in one of the base catalogs. Conversely, the rejection of binaries
depends on their availabilty as such in the relevant catalogues.
Note (2): Magnitude flag:
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 (3): 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.
