 NOTE: keywords must not be abbreviated.  An entry like "KEY" is equivalent to
 "KEY=Y" or "KEY=1".  Key values may be integer or floating point or the      
 letters Y, N, T or F.  Default values are set to the previous entries.       
                                                                              
 The keywords CMIN and CMAX may be used to specify the range of channels to be
 plotted or if for example two non-adjacent channels needed to be plotted,    
 then the keywords C1 and C2 could be used.
