`incidence` and `elevation` variables as 1D ? #71

Open oarcher opened 2 years ago

oarcher commented 2 years ago

incidence and elevation variables are currently 2D, and that could take much memory.

incidence is nearly constant on atrack dim, and elevation is nearly constant on xtrack dim, so they can 1D, ie incidence.shape (xtrack) and elevation.shape (atrack)
