Earth orientation parameters based on EOC-4 astrometric catalog
Original language description
Recently we derived a new star catalog EOC-4 that contains not only the mean positions and linear proper motions, but alsoperiodic changes, due to orbital motions, for double and multiple star systems. This catalog is now used, as a basic celestial frame, to obtain the Earth orientation parameters from optical astrometric observations of latitude/universal time/altitude in the interval 1899.7-1992.0. Polar motion is determined in 5-day steps for the whole interval studied, Universal time covers the interval 1956.0-1992.0 (i.e., after the invention of atomic clocks) also in 5-day steps, and celestial pole offsets (with respect to recent IAU2000 and IAU2006 models of nutation and precession) are modeled by second-order polynomials of time. In addition tothese, a combination of Love and Shida numbers for each observing site is computed.
