I/209A Catalogue of 2700 double stars (Couteau, 1993)
===============================================================================
Catalogue de 2700 etoiles doubles
Couteau P.
<Observatoire de la Cote d'Azur, Departement: Augustin FRESNEL
URA 1361, 2eme Edition Revised (Juin 1993)>
=1993CED27.C......1C (SIMBAD/NED Reference)
================================================================================
ADC_Keywords: Stars, double and multiple
Description:
This catalog contains a compilation of measurements of binary stars
discovered by Paul Couteau between 1951 and 1993. For each star, it
contains a reference number to identify the star in the catalog, the
Cou number, the visual magnitudes of the components, positions for
1900, 1950, and 2000, the identification of the star in the BD or in
the Carte du Ciel, the magnitude from that catalog, remarks such as
the proper motion, a system to which the binary belongs or its
position with respect to a neighboring BD star and for many stars,
the spectral type. For each observation, the data given are the date,
position angle, separation, telescope size, number of observations,
and the observer. Sometimes the magnitudes estimated by the observer
are also given.

Corrections made for CDS:
The files were reformatted for CDS by D. Pourbaix, and many corrections
were performed in agreement with the author. The most important one is:
Cou 135 (obs 2) rho changed to 8.05"
Errata were communicated to the author and concern the following binaries:
5,9,10,11,13,14,19,48,60,63,107,114,135,136,164,165,166,172,174,175,191,

2388,2451,2466,2544,2551,2559,2582,2680
The consistency of the coordinates in the three equinoxes was checked and
corrected when the discrepancy was larger than 3'.
The consistency of the observers' abbreviation with WDS was checked and
corrected
* 15-Jun-1995: a few more errors detected by D. Pourbaix in files "main.dat",
"seq.dat" and "obs.dat":
COU 6, obs 4: instrument size is 29cm (not 29")
COU 5, obs 12: instrument size is 29cm (not 29")
COU 599, obs 1: epoch is 1971.32 (not 1987.132)
COU 2680: 'a' suffix was missing in BD number
COU 358: 'a' suffix was missing in BD number
COU 681: BD number is +22 421 (not +22 241), and SAO 75695
