measurement_vector_fitted
=========================

.. currentmodule:: pyarts3.workspace

.. attribute:: Workspace.measurement_vector_fitted
   :type: ~pyarts3.arts.Vector
   
   As :attr:`~pyarts3.workspace.Workspace.measurement_vector`, but fitted to the model.
   
   This must often be the same size as :attr:`~pyarts3.workspace.Workspace.measurement_sensor`.
   
   See :attr:`~pyarts3.workspace.Workspace.measurement_vector` for more details.
   In that notation, and in the notation of :func:`~pyarts3.workspace.Workspace.OEM`,
   :math:`\vec{y}_f \approx \vec{y} - \epsilon`.
   Or at least this should be the case depending on how good of a fit of :math:`\vec{x}`
   has been produced and if the measurement can be understood properly.
   
   .. tip::
       It is often useful to present :math:`\vec{y} -  \vec{y}_\epsilon`
       and :math:`\vec{y}_f - \vec{y}_\epsilon` instead of
       :math:`\vec{y}_f` and :math:`\vec{y}` directly.  This removes the
       known measurement error from both the data and the fit,
       showing the physical signal from the target rather than
       known sensor noise.
