WSAT 

     WSAT is the ending valid time for the WindSAT wind data, the speed
     intervals and colors, the wind barb size and width and plotting
     flags.  Skip is a value that indicates how many rows and data points
     to skip when plotting.  The flag being used is the Rain flag.

       Data type | End time | Speed intervals | colors1 | colors2 |
       Arrow/Barb shaft size;Arrow/Barb width;Arrow head size;
       Type of wind vector | Skip | Time stamp interval | Time stamp color | 
       Line Width | Rain | Rain Colors | Plot Circles

     The data type is a selection to plot. Currently there is only one data
     type, WSAT. 

     The ending time is the latest time for which WindSAT data will be 
     plotted.  The ending time is given as a GEMPAK date/time string.  Any
     missing items from the string will be filled in by the system time.  The 
     ending time may also be LAST.  LAST will use the system time and plot all
     WindSAT data for the preceding 4 hours. ALL is not accepted as an ending 
     time for WindSAT data.

     The speed intervals and colors may each be specified using either a list
     separated by semicolons or a range in the form first-last-increment.
     Speed intervals are given in knots.  If any color is missing, a default 
     will be used.  If no interval and color are given, a single speed 
     interval of 200 knots will be used.  This means that any wind speed less 
     than 200 knots will be plotted.  The default color for the single speed
     is green.  If the rain flag in the data is true, and the rain colors flag 
     is true, the wind barb is plotted in the second colors for that wind speed.  
     If the rain flag is false or the rain colors flag is false, then the 
     first color is used.

     The wind arrow/barb attributes are the shaft size of the arrow or barb,
     width of the arrow or barb, size of the arrow head, and the type of wind
     vector separated by a semicolon.  The default shaft size is 0.2, the
     default width is 1, the default arrow head size is .4 , and the default
     type of wind vector is 5 for wind barb.  The other values for type of wind
     vector is 1 or 3 for directional arrow and 4 for regular arrow.  If no
     value is given for the type of wind vector, then if the arrow head size is
     greater than 0, directional arrows will be plotted, otherwise wind barbs
     will be plotted.

     The Skip value is an integer used for skipping rows and columns of data
     when plotting the winds.

     The time stamp interval is the time interval in minutes. Line width is
     the width of the time stamp. The default value is 30 time stamp interval
     and 1 for line width.

     The Rain flag corresponds to the Rain affected flag in the WindSAT data.
     The Rain flag allows the user to display wind data that has this attribute.
     The default for this flag is NO. 

     The Plot Circles flag indicates whether circles should be plotted along 
     with the wind barbs/arrows for rain flagged winds.
