            * src/m_cloudradar.cc: Further work.

            * doc/uguide/ppath_theory.tex: Removed references to ppath_array,
            changed to \funcindex for ppath_calc.

            * doc/uguide/rte.tex: Changed reference to ppath_cal to
              ppath_agenda.

              * doc/uguide/ppath.tex: \builtindoc was used for ppath_calc.
              Changed to \funcindex.

              * doc/uguide/winds.tex: doppler_shift -> rte_doppler.

              *
                controlfiles/artscomponents/montecarlo/TestMonteCarloGeneralGaussian.arts:
                *
                controlfiles/artscomponents/montecarlo/TestMonteCarloGeneral.arts:
                cloudbox_checkedCalc called with explicit arguments, as for
                these
                MC-WSMs scat_data_mono replaced scat_data_raw.

                * particle_masses is now a mandatory "cloudbox variable", to
                complement pnd_field and scat_data_raw. However, can be left
                empty if particle mass is not used.

                *
                  controlfiles/artscomponents/montecarlo/TestMonteCarloDataPrepare.arts:
                  pnd_field was non-zero at lat and lon limits of the cloudbox
                  (catched by extension of cloudbox_checkedCalc). Changed lat
                  and
                  lon extension of cloudbox from +-1.8 to +-1.9 deg (following
                  the
                  grid of used raw pnd_field).

                  * controlfiles/general/general.arts: Added particle_masses,
                  set to
                  be empty.

                  * src/m_atmosphere.cc (basics_checkedCalc): Added check for
                    negative
                    values in edensity_field.

                    * src/cloudbox.cc (chk_pnd_field_raw_only_in_cloudbox):
                    Moved from
                    check_input.cc, to be placed beside some very similar
                    functions.

                    * src/m_cloudbox.cc (cloudboxOff): Now also returning an
                      empty
                      particle_masses.

                      (cloudbox_checkedCalc): Now also performing checks on
                      pnd_field
                      and particle_masses. Note that pnd_field is allowed to be
                      >0 for
                      lower altitude limit of the cloudbox, if this point is at
                      or
                      below the suface altitude.

                      * src/montecarlo.cc (iwp_cloud_opt_pathCalc):
                        particle_masses
                        passed on to this function. Also adopted.

                        * src/m_montecarlo.cc (mc_IWP_cloud_opt_pathCalc): Only
                        WSM that
                        used particle_masses. Adopted. Demands that
                        particle_masses has a
                        single column.

                        * src/workspace.cc: Redefined the WSV particle_masses.
                        The scope
                        is now larger and the type is changed from Vector to
                        Matrix.

            * src/m_cloudradar.cc (iyCloudRadar): Added Bacscattering and
            particle field as aux variables.

	* src/cloudbox.cc: Several documentation fixes (particularly units
	of LWC&IWC).

            * arts-2-1-350

            * src/m_cloudradar.cc (iyCloudRadar): Now considering that the
            vector transmission is direction dependent. That is, there is now
            a transmission matrix for the propagation from the transmitter to
            the scattering point, and another matrix for the reversed
            propagation. (Needed as T1*T2 != T2*T1, where T1 and T2 are
            transmission matrices).
            Added round-trip time as aux var.

            * src/m_cloudradar.cc (yCloudRadar): Better handling of aux vars.
