Analysis of modern astrometric catalogues in the Gaia era
VS Akhmetov, PN Fedorov, VS Tsvetkova… - arXiv preprint arXiv …, 2021
We investigate of the systems of proper motions of stars in the ground-based
catalogues HSOY, UCAC5, GPS1 and PMA derived by combining with the Gaia DR1
space data. Assuming the systematic differences of stellar proper motions of two
catalogues to be caused by the mutual solid-body rotation and glide of the
coordinate systems produced by the data of the catalogues under comparison, we
analyse the components of the mutual rotation vector and displacement of the origins …
