:emphasis:`Documentation for data product element DpdNirSuperFlatFrame:`

Super-flat frame to correct the NIR science frames for variations in pixel response to a flat illumination.
This is an alternative approach to flat fielding based on a large number of wide survey science frames.

Processing Element(s) creating/using the data product
=====================================================
.. PECreatorStart

The super-flat is created by a calibration pipeline which combines a large number of wide survey science frames.

The application of the super-flat correction is done using NIR_FlatFieldCorrection PE as for
the small and large scale :ref:`NIRMasterFlat`.

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

The structure of the NIR Super-Flat is the same as the Science Image of the :ref:`NIRCalibratedFrame` with 16 x 3 layers, i.e.
median flat field correction, RMS, and Data Quality flags for each detector.

A super-flat frame for each filter is foreseen. In addition, a set of metadata is used to describe the validity range,
the time interval and the list of science frames used to generate the super-flat.
