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

The DpdExtSingleEpochFrame represents the common data product used by all external ground-based surveys (EXT-PF1 Stage 1)
to deliver their detrended, astrometrically and photometrically calibrated science images to the Euclid SGS.
They are input to EXT-PF1 Stage 2.
Each DpdExtSingleEpochFrame contains for one detector the science image pixel data and the accompanying source catalog
and PSF model.

Three FITS files are included in each DpdExtSingleEpochFrame:

* Image FITS file (FitsFormat id: ext.singleEpochFrame)
* Catalog FITS file (FitsFormat id: ext.sourceCatalog)
* PSF model FITS file (FitsFormat id: ext.psfModel)
