Agenda ppath_agenda
Calculation of complete propagation paths. In contrast to ppath_step_agenda that controls the ray tracing inside each grid box, this agenda determines how complete paths are determined. The standard choice is to do this in a step-by-step manner using ppath_step_agenda, with this agenda set to call ppathStepByStep. The WSV rte_los is both input and output as in some cases it is determined as part of the propagation path calculations (such as forfor radio link calculations). The include file 'agendas.arts' predefines some agendas that can either be used directly, or serve as inspiration.
