.. DetailedDescStart

Also known as **biascor image** in DES terminology. This product is the result of
applying the DES *biascor* pipeline to a set of DES :ref:`DESBiasFrame`\s (bias
exposures). It contains the master bias dataset of a single CCD.

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.
* **CCDNumber**: The DECam science CCD number (1 to 62).
* **DataStorage**: Element that links to a FITS file containing the CCD master bias
  image dataset.
* **RunInformation**: Information about the processing run (Project and RunNumber).
* **ProcessingSteps** (optional): Information about the processing steps associated
  with the *biascor* process.
