Plotting parameters are entered in a freeform manner by way of keywords and
 optional value assignments of the form KEY=value.  Key-value pairs may be
 given in any order separated by spaces or commas.  The following keys are
 recognized by PWS16PC:
 
 KEYWORD  DEFAULT VALUE   EXAMPLE        COMMENT

 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.
 
 EXAMPLE:
 > spacecraft=1 year=79 day=64 span=3.5 cmin=7 cmax=9
 
 The above would plot Voyager 1 data from 79 064 0000 - 0330, channels 7-9,
 (311, 562, 1000 Hz) in default RMS electric field units.
