Problems of Using Hipparcos Astrometry of Double Stars

Abstract

The current optical realization of the International Celestial Reference System is the Hipparcos main catalog in its entirety. This paper demonstrates that a subset of the main catalog stars specifically those marked as double ("C" stars), acceleration solution ("G"), variability induced movers ("V"), and stochastic solution stars ("X") is of much lower quality than the majority of the catalog. Stars marked as suspected doubles ("S") were investigated and found to show few problems. The authors have put forth a resolution (resolution 2, this conference) to remove the C, G, V, and X stars, in addition to the Hipparcos orbit stars ("O stars"), from the optical realization of the reference frame.
