pub fn precess_orb_elements(
    old_inc: f64, 
    old_arg_perih: f64, 
    old_long_ascend_node: f64, 
    JD1: f64,

) -> (f64, f64, f64)

Computes orbital elements reduced to a different equinox

Returns

(new_inc, new_arg_perih, new_long_ascend_node)

  • new_inc : Inclination in the new equinox | in radians
  • new_arg_perih : Argument of perihelion in the new equinox | in radians
  • new_long_ascend_node: Longitude of ascending node in the new equinox | in radians

Arguments

  • old_inc : Inclination in the old equinox | in radians
  • old_arg_perih : Argument of perihelion in the old equinox | in radians
  • old_long_ascend_node: Longitude of ascending node in the old equinox | in radians
  • JD1 : Julian (Ephemeris) day corresponding to the old equinox
  • JD2 : Julian (Ephemeris) day corresponding to the new equinox
