.. currentmodule:: pyarts3.workspace

.. attribute:: Workspace.do_jac
   :type: ~pyarts3.arts.Index

   A boolean calculations related to the :attr:`~pyarts3.workspace.Workspace.measurement_jac` should be ignored.

   This variable is limited to very few methods related to the inversion process for :func:`~pyarts3.workspace.Workspace.OEM`.
   Note that deep code of ARTS will ignore this variable, so it is not a global switch.
   Instead, it is used as a switch to clear the :attr:`~pyarts3.workspace.Workspace.jac_targets` variable, which is used
   to determine the size of the :attr:`~pyarts3.workspace.Workspace.measurement_jac`.  It is important to be careful
   with this, as it will mess with the size of the :attr:`~pyarts3.workspace.Workspace.measurement_jac` and could
   thus lead to runtime errors being thrown in places where unexpected sizes are encountered.
