Workspace Method ppathPlaneParallel


Propagation path calculations for a plane parallel atmosphere.

This method basically assumes that the planet's radius is infinite,
i.e. the planet surface has no curvature. Some consequences of this
   - the mathod can only be used for 1D
   - zenith angles between 89.9 and 90.1 deg are not allowed
   - refraction is always neglected
   - radii in ppath are set to Inf

Notice that the method provides full propagation paths. This means
that ppath_step_agenda is ignored (and thus also refraction).
On the other hand, the method considers the cloudbox exactly as
the standard path calculations.
