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

Also known as **science exposure** in DES terminology. This is an input product to the
DES pipeline. It contains 70 extensions (one for each DECam CCD) with the data of a
single science exposure.

The main elements inside this product are:

* **Observation**: Contains information about the telescope pointing (Telra, Teldec,
  HourAngle, ZenithDistance, Epoch), the observation night and date, and the optical air
  mass.
* **Saturate**: Global saturation threshold valid for amplifiers A and B.
* **Object**: The survey object name. For example, 
  *DES survey hex 906-339 tiling 8, Field 74*.
* **Filter**: The DECam filter name (DECAM_g, DECAM_r, DECAM_i, DECAM_z or DECAM_Y).
* **DataStorage**: Element that links to a FITS file containing the science exposure
  image dataset.
