How to get one count level
================================

One count level can be calculated from g-factor.

The conversion between count rate and the flux is

.. math::

        C_{n,i}^{H} = J_{n,i}^{H} \cdot G_{n,i}^{H} \cdot E_i \cdot \Delta t

Thus, the one count level can be calculated as

.. math::

       J_{0,n,i}^{H} = \frac{1}{G_{n,i}^{H} \cdot E_i \cdot \Delta t}
               
Using :mod:`pyana.cena.cena_flux` module, a simple code can be written as follows.
 
.. code-block:: py 

        import cena_flux
        flx = cena_flux.Count2Flux()

        # one for 16 energy and 7 channels
        one_count_level = [[flx.getFlux(1, ie, id) for ie in range(16)] for id in range(7)]
