New model of precession, valid in time interval 400 thousand years
Vondrák, Jan
New model of precession, expressed in terms of long-periodic trigonometric functions of time is developed, based on numerical integration of motions of the Solar system bodies. Its validity is +/- 200 thousand years from the basic epoch J2000, with the accuracy below one milliarcsecond in the central part and gradually decreasing to a few arcminutes towards both ends of the interval of validity.
