Have you tried experimenting with the IDL 5.0 SCALE keyword in place of
the ISOTROPIC and LIMIT keywords? For example
window, /free, xsize=400, ysize=400
map_set, 90, 0, /azim, scale=225e6, /cont, /grid, /label, /noborder
I've found that the SCALE keyword often gives more pleasing results.
Cheers,
Liam.
