[ncl-talk] problem with dimensions of a variable

[Dennis Shea]

Sorry, I was not paying attention.

Perhaps:

 Latitude    = f->Latitude(:,::2)            ;  *[nscan | 3019] x [npixel |
104*]
 Longitude = f->Longitude(:,::2)
or
  Latitude    = f->Latitude(:,1::2)         ;   *[nscan | 3019] x [npixel |
104*]
  Longitude = f->Longitude(:,1::2)

---
Which is appropriate?
This is 'your' data so starting at 0 or 1 is up to you.
