But technically this isn't "binning", because true binning is 
mutually exclusive.   It's either in this bin or that one.  In this 
case you have OVERLAPPING bins, and not only that but the sensitivity 
curve in each bin is different.   So the same pixel has a signal in 
bin A and a signal in bin B.  There is only one unique point on the 
spectrum that would produce any give signal in both bins.
