Validation of the new Hipparcos reduction
Astronomy and Astrophysics, 2007 Context.A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming accuracies for nearly all stars brighter than magnitude Hp = 8 to be better, by up to a factor 4, than in the original catalogue.
