A catalog of reference stars for long baseline stellar interferometry
The calibration process of long baseline stellar interferometers requires the use of reference stars with accurately determined angular diameters. We present a catalog of 374 carefully chosen stars among the all-sky network of infrared sources provided by Cohen et al. 1999. The catalog benefits from...

| description | The calibration process of long baseline stellar interferometers requires the
use of reference stars with accurately determined angular diameters. We present
a catalog of 374 carefully chosen stars among the all-sky network of infrared
sources provided by Cohen et al. 1999. The catalog benefits from a very good
sky coverage and a median formal error on the angular diameters of only 1.2%.
Besides, its groups together in a homogeneous handy set stellar coordinates,
uniform and limb-darkened angular diameters, photometric measurements, and
other parameters relevant to optical interferometry. In this paper, we describe
the selection criteria applied to qualify stars as reference sources. Then, we
discuss the catalog's statistical properties such as the sky coverage or the
distributions of magnitudes and angular diameters. We study the number of
available reference stars as a function of the baseline and the precision
needed on the visibility measurements. Finally, we compare the angular
diameters predicted in Cohen et al. 1999 with existing determinations in the
literature, and find a very good agreement. |
