  1. Numerical theory ERA-2005of rotation of the Deformable Earth with a Two-Layer Fluid Core(Celestial Mechanics, 2006, in press) WRMS(mas) of fitting to GSFC series 1984-2005 of Celestial Pole offsets dθ sinθ dψ ERA-2005 0.136 0.129 IAU 2000 0.1720.165

  2. Residuals dθ in the angle of nutation for theories IAU 2000 (top) and ERA-2005 (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 (2000-2009) sin(θ) dψ dθ

  6. Observed and predicted corrections to IAU 2000(1984-2019) dψ dθ

  7. Experimental detection ofGeodetic Precession dΨ GRT prediction: dΨ=1.9194“/cy Observed value: dΨ=2.07(9)“/cy
