I've got an update to this problem:

I've now managed to plot the data as a 3D surface using the following
command:

SURFACE, POLAR_SURFACE(dns, zeniths, azimuths)

This works fine, and gives me the sort of data I'm expecting. However,
the POLAR_CONTOUR command still gives me nonsense values! I've noticed
a bit in the IDL help for the POLAR_SURFACE function which says "Note
that the ordering of the elements in the array Z is opposite that used
by the POLAR_CONTOUR routine.", but what does this mean? Does it mean
I need to reverse the array of my z values to use it with contour?
That sounds a little strange...why would that be?

Any help would be much appreciated,

Robin
