pint.orbital.kepler.Kepler2DParameters

class pint.orbital.kepler.Kepler2DParameters(a, pb, eps1, eps2, t0)

Bases: Kepler2DParameters

Parameters to describe a one-object 2D Keplerian orbit.

Parameters:

• a (float) – semi-major axis

• pb (float) – binary period

• eps1 (float) –

• eps2 (float) – eccentricity parameters

• t0 (float) – time of the ascending node

Create new instance of Kepler2DParameters(a, pb, eps1, eps2, t0)

Methods
