1
Numerical theory ERA-2005 of rotation of the Deformable Earth with a Two-Layer Fluid Core (Celestial Mechanics, 2006, in press) WRMS(mas) of fitting to GSFC series of Celestial Pole offsets dθ sinθ dψ ERA IAU
2
Residuals dθ in the angle of nutation for theories
IAU (top) and ERA (bottom)
3
Residuals sin(θ) dψ in the angle of precession for theories IAU 2000 (top) and ERA-2005 (bottom)
4
Differences : ERA- 2005 minus IAU 2000
sin(θ) dψ dθ
5
Observed and predicted corrections to IAU 2000
( ) sin(θ) dψ dθ
6
Observed and predicted corrections to IAU 2000 (1984-2019)
7
Experimental detection of Geodetic Precession dΨ
GRT prediction: dΨ =1.9194“/cy Observed value: dΨ =2.07(9)“/cy
