The correction term is called the nutation in right ascension or the equation of the equinoxes. Thus, GAST = GMST + eqeq. The equation of the equinoxes is given as eqeq = Δψ cos ε where Δψ, the nutation in longitude ...

WebNutation models in particular have reached a high degree of sophistication, taking into account such things as the non-rigidity of the Earth and the effects of the planets; SLALIB’s nutation model (SF2001) involves 194 terms in each of ψ (longitude) and ϵ (obliquity), some as small as a few microarcseconds. WebTo all nutation series since Woolard (1953) the out-of- phase planetary tilt contributions of Table 1 need to be added. To all nutation series since Woolard, a —0.15 mas annual term from the yearly variation of the geodesic preces- sion needs to be added to the nutation in longitude (Voinov 1988; Gill et al 1989; Fukushima 1991).
