You can use /irregular (even though my contour wrapper seems to make a
dog's breakfast out of it...) to plot the data, but it looks "better" on
the plot with sph_scat, how much non-existent data the interpolation has
added I don't know.

In the IDL helpfile example for SPH_SCAT (a sine wave in longitude and
cosine in latitude I think) the circles on the map appear as circles using
SPH_SCAT, but they appear as jaggy polygons (reflecting the data) using
/irregular.
