measurement_vec_error_covmatConstant

Workspace.measurement_vec_error_covmatConstant(self, measurement_vec_error_covmat: CovarianceMatrix = self.measurement_vec_error_covmat, measurement_vec: Vector = self.measurement_vec, value: Numeric) → None

Sets a constant measurement vector error covariance matrix.

The size comes from the nonempty workspace measurement_vec. Use this primitive helper before oemInitFromData(), which consumes both variables. For data already owned by oem, use oemMeasurementCovmatConstant() instead.

Parameters:

  • measurement_vec_error_covmat (~pyarts3.arts.CovarianceMatrix, optional) – Covariance matrix for observation uncertainties. Defaults to self.measurement_vec_error_covmat. [OUT]

  • measurement_vec (~pyarts3.arts.Vector, optional) – The measurement vector for, e.g., a sensor. Defaults to self.measurement_vec. [IN]

  • value (Numeric) – The value of the covariance matrix diagonal. [IN]
