Workspace Method ppathCalc
Description
Stand-alone calculation of propagation paths. Beside a few checks of input data, the only operation of this method is to execute ppath_agenda. Propagation paths are normally calculated as part of the radiative transfer calculations, and this method is not part of the control file. A reason to call this function directly would be to obtain a propagation path for plotting. Anyhow, use this method instead of calling e.g.*ppathStepByStep directly.
