The solution for the Mars spin corrections Δϕ_cor (blue) is zoomed in to the beginning of the orbiter time frame (1999) to the present relative to the final MRO120G spin rate given in Table 4. Shown are the periodic fit to the orbiter time series of Equation (27) (gray), the MGS (cyan), MRO (black), Odyssey 90 day solution using additional tracking data to 2025 September (green), the InSight 30 day spin solution (red), and the MRO120G quadratic solution used as a test (teal).
