Workspace.measurement_vec_error_covmat_observation_systemCalc(self, measurement_vec_error_covmat_observation_system: pyarts3.arts.Matrix | None = None, measurement_gain_mat: pyarts3.arts.Matrix | None = None, measurement_vec_error_covmat: pyarts3.arts.CovarianceMatrix | None = None) → None

Calculates the covariance matrix describing the error due to uncertainties in the observation system.

The uncertainties of the observation system are described by measurement_vec_error_covmat, which must be set by the user to include the relevant contributions from the measurement and the forward model.

Prerequisite for the calculation of measurement_vec_error_covmat_observation_system is a successful OEM() computation where also the gain matrix has been computed.

Parameters:

  • measurement_vec_error_covmat_observation_system (Matrix) – Covariance matrix describing the retrieval error due to uncertainties of the observation system. Defaults to create and/or use self.measurement_vec_error_covmat_observation_system : Matrix. [OUT]

  • measurement_gain_mat (Matrix, optional) – Contribution function (or gain) matrix. See measurement_gain_mat, defaults to self.measurement_gain_mat [IN]

  • measurement_vec_error_covmat (CovarianceMatrix, optional) – Covariance matrix for observation uncertainties. See measurement_vec_error_covmat, defaults to self.measurement_vec_error_covmat [IN]
