orbix.kepler.shortcuts.guess#
Methods for generating initial guesses for the eccentric anomaly.
E_guess returns the initial guesses for the eccentric anomaly calculated from the constructed polynomials defined by RPP and orvara, based on the mean anomaly and eccentricity. There is also a jit-compiled version available as E_guess_jit.
