============================

.. py:module:: orbix.kepler.shortcuts.guess

.. autoapi-nested-parse::

   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`.
