First Double Star Observations in the HIPPARCOS Tycho Project
Published online by Cambridge University Press: 12 April 2016
Abstract
The Tycho project will provide positions and (B, V) magnitudes for about 1 million stars, and will be complete for stars brighter than magnitude (B + V)/2 = 10.5. The components of double stars will obtain individual measurements when the separations are wider than 3″.
