GET/FIT table [image]
	create a table for fitting subimages
\us\pu
Purpose:      
              Read the rectangular cursor to define subimages and initial
              guesses for fitting those with certain functions
\up\sy
Syntax:       
              GET/FIT table [image]
\ys\pa
              table = name of the table that is used to store the values
                      provided by GET/CURSOR
\ap\pa
              image = optional image from which the pixel values are taken.
                      By default the currently loaded image is taken.
\ap\no
Note:         
              The values :XSTART, :XEND, :YSTART and :YEND are used later on
              to extract as many subimages as entries are put into the table.
              Four values are then determined: :I0, :X0, :Y0 and :BACK. They
              are the maximum intensity in the subimage corrected for the
              background, the x and y where this maximum occurs and an
              estimate for the background intensity. The table will also
              contain the local averages in 3 x 3 pixel areas at the four
              corners of the subimages in columns :BACK_1 to :BACK_4.
\\
              On DeAnza Image Display the cursor box has to be set up as:
              both cursors on, TRACK off, RATE on.
