I was hoping to add the MC data as color to the MM data for Lum. Perhaps this is not a thing though.
So to get around the issue of not being able to register OSC and mono data together, you can load the OSC data, split it into RGB data which would give you 3 sets of data (red, blue, and green) those 3 sets of data would be mono.
Take one set, and register the 1600mm data to the red channel set of the OSC data. Now you'll have R G B and L with the same alignment.
How you proceed from there depends on how you want the process the data. You can combine it all as LRGB in APP, Pi, Ps or whatever you use for post processing.
Thanks Reginald, that is the path I was going down next.
