Periodic errors of stellar abscissae in the HIPPARCOS experiment caused by oscillations of the basic angle

Makarov, V. V.

The problem of stellar abscissae error propagation originating from systematic variations of the basic angle during one turn of the Hipparcos satellite is investigated within the framework of a general data processing algorithm. These variations may be caused by systematic irregularities of the heat flux from solar radiation as the satellite's opt…
