Signature in the Doppler observable of the relativistic corrections in the longitude angle ψ: (a) Signature in the Doppler observable (in μm s⁻¹) of the small geodetic nutations in the longitude angle as a function of time, using the RISE timing (Nov. 2018–April 2022). The blue envelope uses a simulated continuous timing. The gray dashed line represents the geodetic nutations, arbitrarily rescaled. (b) Signature in the Doppler observable (in mm s⁻¹) of all the geodetic terms (nutations and the linear term), using the RISE timing.
