.. py:function:: get_gc_intersect(s1, s2)

   Given two great circles, specified by their poles, find the two intersection points.
   :param s1: Pole of first great circle as Skypos object
   :param s2: Pole of second great circle as Skypos object
   :return: A list of the two Skypos objects representing the two intersection points.
