spectral_rad
============

.. currentmodule:: pyarts3.workspace

.. attribute:: Workspace.spectral_rad
   :type: ~pyarts3.arts.StokvecVector

   A spectral radiance vector.

   This is the representation of the spectral radiances at discrete frequencies for
   a discrete viewing direction.

   The unit of spectral radiance is [W / m :math:`^2` sr Hz].

   Note that there are conversion routines that changes this unit,
   e.g., :func:`~pyarts3.workspace.Workspace.spectral_radApplyUnit`.  After conversion,
   the use of :attr:`~pyarts3.workspace.Workspace.spectral_rad` in any method no marked as safe for different units,
   will lead to undefined behavior with possibly bad values being computed.

   The size of this variable should be the size of the local :attr:`~pyarts3.workspace.Workspace.freq_grid`.
