Validation of the new Hipparcos reduction
@article{Leeuwen2007ValidationOT, title={Validation of the new Hipparcos reduction}, author={Floor van Leeuwen}, journal={Astronomy and Astrophysics}, year={2007}, volume={474}, pages={653-664} }
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 catalog ue. Aims. The new Hipparcos astrometric catalogue is checked for the quality of the data and the consistency of the formal errors as well as the possible presence of error correlations. The differences with the earlier publication are explained. Methods…

Abstract The formal errors on the astrometric data in the 1997 publication of the Hipparcos catalogue are, for stars brighter than about magnitude 9, largely the result of inaccuracies in the…
Building the cosmic distance scale: from Hipparcos to Gaia
