I don't know if it's an error but my understanding of the normalisation process is to align the lowest point of all subs (usually close to black point) to a common point then scale the distribution of all the data sample equaly in all the frames.
So if you have all your red subs, of course you normalise them prior to do data rejection and stacking but if you have a master red and a master blue let's say and the object has a lot of red in it and hardly any blue, if you normalise the blue to the red you're going to stretch the hell out of it and if you normalise the red to the blue you're going to kill the dynamic range in the red because you're going to compress all the red samples within the 'narrower' range of the blue. Unless I got it all wrong? Maybe some guru can pitch in.
