Mesures d'étoiles doubles et précision des coordonnées équatoriales; Mesures d'étoiles doubles et précision des coordonnées équatoriales; Measures of visual double stars and precision of equatorial coordinates
Abstract
We present 287 measures of visual double stars (position angle, separation and coordinates). These measures have been made with a 8 inches Takahashi Cassegrain telescope CN212, for a focal length of about 2.70 meters. Frames have been obtained on a CCD camera Sbig ST7E. These measures complete also the CCDM catalogue. The results are displayed in three tables, dedicated to the position angle and the angular separation (Table 1), the precision of equatorial coordinates J2000.0 (Table 2) and the differences of equatorial coordinates with the WDS index (columns 113-130) (Table 3), respectively.
