Range...ok, just change the ranges I gave from 'whole world' to 126-130
long, 36-38 lat, or whatever the data really is, change GS=[10,5] to
GS=[0.1,0.05] or something, depends on the resolution YOU want.

Ah, fun with maps..

map_set, /mercator, limit=[lower_long, lower_lat, upper_long,upper_lat]
contour,r,x,y, /over

; you will have to play with the contour and the map_set to get the image
; you want, check the helpfile for continent and lat-long lines plotting.

Whether you use the SPH_SCAT or the /irregular keyword on contour, the map
projection method is the same.

Chris.
