seamfix
-------

What it does:  Allows for interactive adjustment of factors to multiply each
               individual column by, in the as-of-yet most successful attempt
               at reducing the seam effect noticed at the edges of the sensors.

Controls:      Start by using the left mouse button to drag a horizonal region
               in the main (left) draw area.  The average intensities of the
               column data within this region is graphed below.  The data
               points on the graph can be dragged up and down to modify the
               factors by which the image to the right is multiplied.  If you
               want to 'zoom in' on the data to modify it more precisely or to
               see it more clearly, use the right mouse button to drag a window
               around the desired region in the graph.  The full view can be
               restored later by pressing the 'zoom out' button. By default the
               graph below shows the original (in light blue) data and the
               modified (darker blue) data in terms of linear intensity.  To
               instead see the factors themselves, press the 'graph factors'
               button.  The save factors button will store the current factors 
               so the same numbers can be applied to other FITS files to see 
               if the seam effect is consistent from one frame to another.  You
               also have the option of saving the modified image back out to a
               FITS file.

Notes:         None.
