    • Method Detail

      • getParametersDrivers

        public List<ParameterDriver> getParametersDrivers()
        Get the drivers for parameters.

        All the parameter drivers of all Estimated models are returned in an array. Models are ordered chronologically.

        Specified by:
        getParametersDrivers in interface ParameterDriversProvider
        Returns:
        drivers for parameters
      • addTroposphericModelValidBefore

        public void addTroposphericModelValidBefore​(EstimatedTroposphericModel model,
                                                    AbsoluteDate latestValidityDate)
        Add an EstimatedTroposphericModel entry valid before a limit date.
        Using addTroposphericValidBefore(entry, t) will make entry valid in ]-∞, t[ (note the open bracket).
        Parameters:
        model - EstimatedTroposphericModel entry
        latestValidityDate - date before which the entry is valid (must be different from all dates already used for transitions)
      • addTroposphericModelValidAfter

        public void addTroposphericModelValidAfter​(EstimatedTroposphericModel model,
                                                   AbsoluteDate earliestValidityDate)
        Add a EstimatedTroposphericModel entry valid after a limit date.
        Using addTroposphericModelValidAfter(entry, t) will make entry valid in [t, +∞[ (note the closed bracket).
        Parameters:
        model - EstimatedTroposphericModel entry
        earliestValidityDate - date after which the entry is valid (must be different from all dates already used for transitions)
