The Hipparcos parallax for Polaris.

VAN LEEUWEN F.

Abstract (from CDS):

This Letter follows a recent claim that the Hipparcos parallax for Polaris could be too small by 2.5mas. It examines in detail the Hipparcos epoch astrometric data for Polaris, as well as the viability of other observations that were put forward to support a larger parallax. The Hipparcos determination of the Polaris parallax is shown to be sufficiently robust to fully exclude a significantly larger parallax, and there is no observational support from other observations, such as a supposed presence of a cluster, either.
