interpolate_redshift_locations
==============================

.. py:method:: luminet.isoradial.Isoradial.interpolate_redshift_locations(redshift)

   Calculates which location on the isoradial has some redshift value (not redshift factor)

   In general, either two or zero solutions exist.
   A notable exception is the tip of an isoredshift, which may only touch the isoradial and not intersect, yielding only one solution.

   :Parameters: **redshift** (*float*) -- Redshift value

   :returns: Tuple[:class:`~numpy.ndarray`] -- 2-tuple containing the angles and radii for the redshift value.
