pint.orbital.kepler.true_from_eccentric(e, eccentric_anomaly)[source]

Compute the true anomaly from the eccentric anomaly.

Parameters:

  • e (float) – the eccentricity

  • eccentric_anomaly (float) – the eccentric anomaly

Returns:

  • true_anomaly (float) – the true anomaly

  • true_anomaly_de (float) – derivative of true anomaly with respect to e

  • true_anomaly_prime (float) – derivative of true anomaly with respect to eccentric anomaly
