Questions about drag cd

# Drag
drag:
  cd:
    values: [2.0, -10.0, 10.0]
    isEstimated: true

values: [2.0, -10.0, 10.0] ：Why are there three values to modify, and what are the latter two for?

Hi @newWL

The first one is the parameter’s value. The two other ones represent the minimum and maximum allowed values.

The information is available in the header of the YAML file:

# Estimated parameters (clock offsets, atmospheric parameters, etc.)
# are set into an array given by [initialValue, minValue, maxValue]

Minimum and maximum values are used to limit the value of the parameter during the estimation process.

Bryan
