Determination of some parameter for wfr
======================================

if you look at inputwfr_sim.txt in teh TEST directory you will see that :

        * pixels_per_degree   = None

This because None triggers the evaluation of some parameters, for this case that is simulated,
 in a different way then in the experimental case.

Look at ParametersR_module.py to see how this is done

In the experimental case you have to use the simpel script
