   4   *Predefined name*. This key indicates the quality criterion, minimized to
   5   find the optimal state estimate. The default is the usual data assimilation
   6   criterion named "DA", the augmented weighted least squares. The possible
   7   criterion has to be in the following list, where the equivalent names are
   8   indicated by the sign "<=>":
   9   ["AugmentedWeightedLeastSquares" <=> "AWLS" <=> "DA",
  10   "WeightedLeastSquares" <=> "WLS",
  11   "LeastSquares" <=> "LS" <=> "L2",
  12   "AbsoluteValue" <=> "L1",
  13   "MaximumError" <=> "ME" <=> "Linf"].
  14   See the section for :ref:`section_theory_optimization` to have a detailed
  15   definition of these quality criteria.
