Corrections to the Hipparcos Proper Motions in Declination for 807 Stars

Damljanovic, G.; Pejovic, N.

We used the data on latitude variations obtained from observations with 10 classical photographic zenith tubes (PZT) in order to improve the Hipparcos proper motions in declinations µ_{δ} for 807 stars. Part of observing programmes, carried out during the last century for the purpose of studying the Earth's rotation, were realized by using P…
