.. DetailedDescStart

Also known as **coadd** in DES terminology. This product is the result of applying the
DES *coadd* pipeline to a set of DES :ref:`DESCalibratedFrame`\s (single epoch images).

The main elements inside this product are:

* **Instrument**: The instrument name (DECam) and telescope name (NOAO).
* **Filter**: The DECam filter name (DECAM_g, DECAM_r, DECAM_i, DECAM_z or DECAM_Y).
* **WCS**: The image astrometric parameters with linear (e.g., CTYPE1, CRVAL2, CRPIX1,
  CD1_1) and, optionally, non linear terms (PV1_0, PV2_0, ...).
* **ZeroPoint**: The photometric reference zero point in magnitude units.
* **ImgSpatialFootprint** (optional): The spatial footprint of the image either in a
  serie of vertex or a bounding box.
* **Masks** (optional): Euclid bit masks present in the flag image dataset.
* **Saturate**: Global saturation threshold valid for amplifiers A and B.
* **Scamp**: Information about the Scamp processing.
* **DataStorage**: Element that links to a FITS file containing the coadd image, flag
  and weight datasets.
* **PsfModelStorage**: Element that links to a FITS file containing the coadd PSF model.
* **RunInformation**: Information about the processing run (Project and RunNumber).
* **ProcessingSteps** (optional): Information about the processing steps associated
  with the *coadd* process.
