Photon
======

.. py:class:: luminet.photon.Photon(radius, alpha, impact_parameter, z_factor=0.0, flux_o=0.0)

   .. py:attribute:: radius


   .. py:attribute:: alpha


   .. py:attribute:: impact_parameter


   .. py:attribute:: z_factor
      :value: 0.0


      Redshift factor of the photon. This is usually calculated vectorized by the :class:`~luminet.black_hole.BlackHole` class


   .. py:attribute:: flux_o
      :value: 0.0


      Observed flux of the photon. This is usually calculated vectorized by the :class:`~luminet.black_hole.BlackHole` class
