Data Products in SAS
====================

ESA is not serving all the SGS data products in the Euclid :term:`SAS`, but only a subset of them. For each SGS product that is served through :term:`SAS`, each FITS file that belong to the product will be served. For example, for the :ref:`DpdVisCalibratedQuadFrame <VISCalibratedQuadFrame>, you will find:

* the VIS individual exposure FITS file with its SCI, RMS and FLG numerous extensions (one per quadrant).

* the VIS weight map FITS file.

* the VIS Background map FITS file.

* the VIS PSF FITS file.

What is missing in the :term:`SAS` is all the metadata around :term:`DPS` that allow for the :term:`SGS` pipelines to query in detail the data and run on selected subsets.

That being said, the documentation given here in the :term:`DPDD` applies to the version of the products hosted in the SAS. The following sections give the list of the products available in the Q1 SAS instances.
