Precession matrix based on IAU (1976) system of astronomical constants.
Abstract
Summary. At its XVIth General Assembly held in Grenoble in 1976, the International Astronomical Union (IAU) adopted a new value for the speed of general precession in longitude, and it adopted a new basic epoch for future almanacs and ephemerides. In this paper we develop numerical values of the precession parameters and of the precession matrix which enable one to precess to and from J2000.0. Key words: precession - astronomical constants
