public static double calcSNom(double xi,
                              double precRate)
```
    Calculates the nominal speed of the z axis in solar motion units, as function of the precession rate precRate [rev/yr] and the solar aspect angle xi [rad]. This method implements Eq. (26) in FM-037-2, accurate to O(1/K^12).
    
    Parameters:
    
    xi - solar aspect angle [rad]
    
    precRate - precession rate [rev/yr]
    
    Returns:
    
    nominal speed (S)
