Corrections to the Hipparcos Proper Motions in Declination for 807 Stars
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 $mu_{delta} $ for 807 stars. Part of observing programmes, carried out during the last century for the purpose of stud...
