Improved First Estimates to the Solution of Kepler's Equation
arXiv:2108.03215
Abstract
The manuscripts provides a novel starting guess for the solution of Kepler's equation for unknown eccentric anomaly E given the eccentricity e and mean anomaly M of an elliptical orbit.
Version 3: evaluates guesses from a Runge-Kutta-Fehlberg integrator of the diff. eq
