You have not understood me.  I know nothing about what you are doing - 
are you reducing q band or 4 band data?  It took you providing us your 
calibrated data set before we could find the problem last time.  And in 
finding that problem we did re-examine the code very closely and found 
nothing more to correct.  What parameters are you actually using for the 
imaging and CLCOR?

Note that I will be unavailable until March at this point.
