These are the default values for the parameters listed (or, at least, that is how I read this). I believe that the idea is that you can do cross sections for any parameter in a GRID dataset, and you can specify default things (unit, cint, color dash, lint, lsize, smooth) in context files on a parameter by parameter basis. I havn't played with this much yet, so I can't guarantee anything, but I think that the intention was for the user to be able to specify anything. >What I have are grids we have made with PV (potential vorticity) >derived (and explicit grids of theta too).
