Linear Fit?
« on: 2019 March 22 13:13:10 »
Hey guys,
When you do a linear fit to the RGB, do you fit the two weaker colours to the strong one?  Or the two strongest to the weakest one?  Or some other order?
For that matter, do you linear fit the L into this too?

Many thanks, Steve

I usually fit the outside two colours to the middle one

I learned on a workshop, LF reference is the brightest (or low-noise) image,  maybe more saturated stars but no color fringes.
