CONAN.utils.get_orbital_elements.get_Rsky
=========================================

.. py:method:: CONAN.utils.get_orbital_elements.get_Rsky(aR=None, inc=None)

   Get the projected distance of the planet from the star in the orbital plane
   following the equations in Winn 2010 (https://arxiv.org/abs/1001.2010).
   Also return mask of transit and eclipse phases.

   :param aR: semi-major axis over stellar radius
   :type aR: float, None;
   :param inc: inclination in radians
   :type inc: float, None;

   :returns: * **rsky** (*array-like*) -- projected distance of the planet from the star in the orbital plane
             * **y** (*array-like*) -- coordinates of the planet in the orbital plane. y>=0 is the transit phase.
