			       GA

       GAUSTA is a module which computes the mean, mean error, mean error 
 of the mean error, and mean square from a rectangular area of a map.  The
 coordinates are input manually or by the TV cursor-box.  A plot of the
 true distribution or  of the residuals along with a computed gaussian
 having the same sigma and the same scaling in the Y direction can be
 made on a graphics terminal.  A printed output is available in the log
 file.
