 axeswidth=1            width (in points) of axes                
 ticwidth=axeswidth     width (in points) of tic marks           
 gridwidth=axeswidth    width (in points) of grid lines          
 style=seismic          normal (axis 1 horizontal, axis 2 vertical) or 
                        seismic (axis 1 vertical, axis 2 horizontal)   

 Note.                                                     
 The line width of unlabeled contours is designed as a quarter of that 
 of labeled contours.                                      

 All color specifications may also be made in X Window style Hex format
 example:   axescolor=#255                                 

 type:   sudoc pscontour    for more information                 


Notes:

 For nice even-numbered contours, use the parameters  fc and dc

 Example: if the range of the z values of a data set range between
 approximately -1000 and +1000, then use fc=-1000 nc=10 and dc=100
 to get contours spaced by even 100's.
