*#### NOTE to save the postscript plots so that they look 
   good enough to be worth sftp'ing and printing, you shoulds
   specify the size of the graph that you want, using 
   GOPTIONS as above, and then print to file, with Postscript
   (I used Postscript level 2 with good results), and then 
   specify the file you want to save to in your home WAM directory,
   somethoing like Graphout.ps.              #########  ;
