Detailed description of the data product

Large Flat Calibration Pipeline result, using a series of self calibration exposures to calculate a Large Flat to be used in ou-vis science pipelines.

Currently it identifies a field and observes it repeatedly with random pointings, thus the Largeflat product is heavily reliant on its modelling based on the results of Astrometry and positions form the Crossmatch.

The final product will be 36 extensions based on the detectors with the EXTNAME noted as the CCDID.SCI, 4096x4136 pixels.

The fianl product will store as part of the parameters the Uncertainties fits file that is the same size as the primary product.
