Detailed description of the data product

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)

FitsFormat id: ext.singleEpochFrame
