     Total flux may be determined by IMEAN.  To do one plane of an
image set BLC=0,0,n; TRC=0,0,n where n is the plane that you desire.
Do the same for CNTR or any other task when you want one plane.

    Are you really saying that the image is only 3 pixels by 3 pixels????

cubes, and 

   Use SUBIM with BLC and TRC as above.
