FFIELD/IRAC obj_frame ff_frame out_frame 
	Flat Field an IRAC frame
\us\pu
Purpose:      
	Flat fields a data frame by dividing it by a previously
	generated flat field
\up\sy
Syntax:       
	FFIELD/IRAC obj_frame ff_frame out_frame 
\ys\pa
	obj_frame = name of the object frame
\ap\pa
	ff_frame  = name of flat field frame
\ap\pa
	out_frame = name of output frame
\ap\no
Note:        
	This command divides the input frame by the flat field frame and
	sends the result to the output frame. The flat field frame should 
	have previously been calculated using make_iracflat or by
	using COMPUTE/IMAGE, and should be normalised to 1.

Examples:
\ex
        FFIELD/IRAC im0010 kflat imf0010
        Use the flat field kflat to flat field the frame 
        im0010. The output frame is imf0010
