Detailed description of the data product
========================================
.. DetailedDescStart

Data product definition referencing a JSON file containing a dictionary with one gain value in e-/ADU per quadrant.

The calibration pipeline consists at measuring the ratio of the mean signal versus square of the
standard deviation fluxes differences of two flat field pair in the photon transfer curves (PDC).
 
This flat field has been corected from bias.
As we are at low fluxes, it not be necessary to correct from non-linearity and brighter-fatter.
