************************************************************************** Repository of data supporting the results in Daher et al.

The ocean tide simulations employ Earth rotation rates ranging from 6-24 hours. The timesteps in the "integration_results" files have units of seconds and should be divided by 86400*365.25*10^9 to obtain units of Ga. The StateVector variables consist of (1) sidereal Earth rotation rate (s^-1). To obtain Earth rotation period in hours in a Matlab code, type: (1/3600)*2*pi./StateVector(:,1) (2) obliquity (radians). To obtain obliquity in degrees in a Matlab code: (180/pi)*StateVector(:,2) (3) semimajor axis (meters). To obtain semimajor axis in Earth radii in a Matlab code: (1/6378136)*StateVector(:,3) (4) eccentricty (dimensionless) (5) inclination (radians). To obtain inclination in degrees in a Matlab code: (180/pi)*StateVector(:,5) The "ExtraDiagnostics" file contains "ExtraDiagnostics" structures for the Earth-Moon evolution results that employ the four different ocean basin geometries, as described above. The "ExtraDiagnostics" structures include the timesteps (units seconds) as well as several other variables: n (lunar mean motion, units s^-1): (1/86400)*2*pi./ExtraDiagnostics.n_ode45 gives the period of the lunar mean motion in days domegabardt (rate of change of longitude of perigee, units s^-1): (1/(86400*365.25))*2*pi./ExtraDiagnostics.domegabar_dt_ode45 gives the period in years dOmega_dt (nodal rate of change, units s^-1): -(1/(86400*365.25))*2*pi./ExtraDiagnostics.dOmega_dt_ode45 gives the period in years; negative sign added to make the results positive xi_Moon_coremantledissipation: dimensionless parameter xi (see text) KoverC_Moon_coremantledissipation: as with xi, this is another key parameter in the luner core-mantle boundary (CMB) terms (see text) I (lunar equatorial tilt, units radians): (180/pi)*ExtraDiagnostics.I_lunartilt_ode45 gives the lunar equatorial tilt in degrees dpsi_dt (precession period, units of s^-1): (1/(86400*365.25*1000))*2*pi./ExtraDiagnostics.dpsi_dt_ode45 gives the precession period in kiloyears ksinchi_diurnal (diurnal ksinchi values, dimensionless): ExtraDiagnostics.ksinchi_diurnal_ode45 gives the diurnal ksinchi values ksinchi_semidiurnal (semi-diurnal ksinchi values, dimensionless): ExtraDiagnostics.ksinchi_semidiurnal_ode45 gives the semi-diurnal ksinchi values M2_powerdissipation_ode45 (M2 power dissipation, units Watts): (1/(10^12))*ExtraDiagnostics.M2_powerdissipation_ode45 gives M2 dissipation in Terrawatts O1_powerdissipation_ode45 (O1 power dissipation, units Watts): (1/(10^12))*ExtraDiagnostics.O1_powerdissipation_ode45 gives O1 dissipation in Terrawatts The "WriteOut" file contains additional diagnostics for the Earth-Moon trajectories that employ ocean tide simulations with the four ocean basin geometries. These diagnostics are used in Figure 9, which plots d/dt of a, i, and e due to the tides on Earth and to tides and core-mantle dissipation within the Moon. These diagnostics are also used in Figure 10, which plots torques. The Matlab files plot_Figure6.m plot_Figures_7_8_9_11.m plot_Figure10.m create Figures 6-11 of the paper, e.g., the figures representing the main orbital dynamics results ---------------------------------------------------------------------------- ** REFERENCE: Daher H., Arbic B.K, Williams J.G., Ansong J.K., Boggs D.H., et al.
