Ahh, sorry I was referring to Maxim DL 4... Don't have access to Maxim 5 at the moment, but should be X=0, Y=1.
In any case, and since software behaves so differently, it's easy to test correct offsets. Just focus on a colorful target and experiment a bit until you get correct color. Also, note that the use of a IR block filter will help getting better color.
