Workspace Method iyLoopFrequencies
Description
Radiative transfer calculations one frequency at the time. The method loops the frequencies in f_grid and calls iy_sub_agenda for each individual value. This method is placed in iy_main_agenda, and the actual radiative ransfer method is put in iy_sub_agenda. A common justification for using the method should be to consider dispersion. By using this method it is ensured that the propagation path for each individual frequency is calculated. Auxiliary data (defined by iy_aux_vars) can not contain along- the-path quantities (a common ppath is not ensured). The returned ppath is valid for the last frequency.
