Hi Kate,

Please see the attached script (that uses dummy data), and the
resultant PostScript file. This script plots the data by first plotting
the lower third of the values, then the upper third. It also
makes sure no values are plotted between 360 and 0.

The PS file contains the original plot, where you can see the contours
appearing between 360 and 0. The second plot has this removed.

Let me know if this is not what you're looking for.
