Double Star Measures Using the Video Drift Method - III

Le résumé fourni par la source

This paper gives the position angle and separation for 242 multiple star systems measured using the video drift method. Standard deviations averaged 0.59 for separation, 1.8° for position angle for single drifts. The drift method generates a Cartesian (x,y) coordi- nate pair for each star for each video frame during the drift to derive position angle and separation. Many doubles had multiple drifts done over several nights resulting in 4,000 - 10,000 (x,y) pairs analyzed per system. Doubles with multiple drifts/nights combined gave probable errors of 0.10 in separation and 0.27° in position angle. An image intensifier was used on some doubles to reach fainter systems in which WDS catalog magnitudes were in the +13 to +15 range. The systematic accuracy of this method is discussed with multiple drifts over several nights.
