I'm using 0-360 degree coords to work across the 180 meridian. It works
for vector data, and I believe the CVS source has been patched to enable
this for raster and site data. The list archives from a couple of weeks
ago will have a record of this.

Note that although with a display region of 170-190 X axis no site
data east of 180 (ie: 180-190) data displays in the X monitor using V5.0,
it is successfully queried, so the problem was a display rather than data
management one as far as I can tell.
