CONAN.utils.sesinw_secosw_to_ecc_omega#

CONAN.utils.sesinw_secosw_to_ecc_omega(sesinw, secosw, angle_unit='radians')#

Convert sesinw and secosw to eccentricity and argument of periastron in angle_unit

Parameters:

  • sesinw (array-like) – sqrt(ecc)*sin(omega)

  • secosw (array-like) – sqrt(ecc)*cos(omega)

  • angle_unit (str) – unit in which to return the argument of periastron. one of [“radians”, “degrees”]. Default is “radians”

Returns:

  • ecc (array-like) – eccentricity

  • omega (array-like) – argument of periastron in angle_unit
