Precision Of Parallaxes From Automatic And Manual Measures From New Parallaxes Of The Hyades Cluster Region
Published online by Cambridge University Press: 03 August 2017
Abstract
Measures of 25 members of the Hyades and about 260 field stars have been made for parallax and proper motion in two ways, automatically using a PDS microdensitometer and manually using a conventional measuring machine. Reductions show the parallax errors from the former are about half those of the latter method.
