pint.orbital.kepler.Kepler3DParameters

class pint.orbital.kepler.Kepler3DParameters(a, pb, eps1, eps2, i, lan, t0)

Bases: Kepler3DParameters

Parameters to describe a one-object 3D Keplerian orbit.

Parameters:

• a (float) – semi-major axis

• pb (float) – binary period

• eps1 (float) –

• eps2 (float) – eccentricity parameters

• i (float) – inclination angle

• lan (float) – longitude of the ascending node

• t0 (float) – time of the ascending node

Create new instance of Kepler3DParameters(a, pb, eps1, eps2, i, lan, t0)
