            * arts-2-1-410

            * doc/uguide/transmission.tex: A first complete version of
            14.2.2-4 written.



git-svn-id: https://www.sat.ltu.se/svn/rt/arts/trunk@8067 aaf1aab0-4228-0410-ad68-8dceda47f409
	* arts-2-1-411

	* src/m_cloudbox.cc (pnd_fieldExpand1D): Bugfix - lon-dim calc of
	expanded cloudbox had a typo. Remove cloudbox_checked as input -
	that didn't deliver any additional security  (cloudbox_checkedCalc
	should anyway be done on the expanded fields again), but required some
	else unnecessary, messy settings before (e.g. cloudbox_checkedCalc
	requires basics_checked, which requires z_surface to be set, i.e.,
	requires to set 1D z_surface and update/change to 2/3D later on.)

	* src/methods.cc: Adapted pnd_fieldExpand1D according to above.
	Additional minor fixes (cross-links, ...) on doc in a number of methods.

            * arts-2-1-412

            * doc/uguide/transmission.tex: More writing (including stuff not
            yet implemented!).

            * arts-2-1-413

            * doc/uguide/transmission.tex: Fixed types found at a quick
            reading, and removed obselete parts of the additional defocusing
            section.

            * arts-2-1-414

            * controlfiles/artscomponents/radiolink/TestRadioLink2.arts:
            Adopted, selecting defocusing method 2.

            * src/m_rte.cc (iyRadioLink): The method considers now also
            particle extinction, including aux vars. Defocusing method can be
            selected by the user.

            * doc/uguide/transmission.tex (subsection{Extra path delay}):
            Removed the idea about returning dn/c.

            * arts-2-1-415

            * src/m_rte.cc (iyRadioLink): Started on Faraday rotation.

            * src/rte.cc (get_ppath_abs): Adopted to below. The [-1] option
            would never happen.

            * src/workspace.cc: Changed description if rte_mag, mainly
            removing the option of [-1].

            * arts-2-1-416

            * src/m_rte.cc (iyRadioLink): Some more work on Faraday rotation.
            Mainly to figure out the correct combination of basic constants
            (e, m, c etc.) when using SI units. The factor 2.34e4 given in
            several places, is now calculated from fundamental constants.

            * arts-2-1-417

            * src/m_rte.cc (iyRadioLink): More work on Faraday rotation.
            Overall code is in place, but Ne not yet included in the
            calculation.

            * src/check_input.cc (chk_rte_pos): Check of rte_pos2 demanded 1D
            latitudes to be inside +-90. Higher values are needed when working
            with links to GPS datellites. Limit now set at 180 deg.

            * src/rte.cc (defocusing_sat2sat): Had to change the way correct
            usage is checked, as with ionopshere a satellite can be inside the
            model atmosphere.

            * src/m_basic_types.cc (Tensor4AddScalar): Created, following the
            corresponding WSM for Tensor3.
