Can you say what you mean by this?

Sorry, I wasn't paying attention.  Raw scans are precisely the data out of
the A/D, but "justified" in a 16 bit space, if the A/D is over 8 bits.
There really is no standard for this, but I'd believe that low bit
justifying the data might be the best way, as it's easier to work with for
setting setpoints.

The raw data does not have setpoints set, or tonal curves applied...

Nope.
