Time-critical
-------------
No

Objective
---------
Update the zodi model based on routine wide survey fields. This will not sample the full ecliptic longitude and latitude space, but
at least the range that we routinely observe.

Fulfilled by
------------
:ref:`calobs-block-pv-zodimodel`

:ref:`calobs-block-f-wide-survey`
     
Data volume
-----------

``38*VS = 17176 MB``

Processing input
----------------
:command:`Ground Processing Input Data`:

:command:`Data Description`: 

Validation
----------
Compare the prediction of the zodi model with the currently observed values at a given ELON and ELAT position.
Update the zodi model if necessary. See also :ref:`char-survey-zodimodel`.
