I have noted what at the subject (regardless I flag or the augmented data flag the process and the generated LUT is the same).
I have looked at the manual, but I could find nothing that warns me about.

Honestly I have to rely on Steve to know if it is correct (He is the only expert in LUT generation I know!).
The reason I post in this thread, is that, if that is true, it would nice to have the augmented data option grey out (just for avoiding other guys to make the same mistake)

Anyhow, it would nice for me the opposite (i.e. being a bug), as my goal was to trying fix a grey scale that come poorly from a fit space option.

I have attached the related bcs for replication.

No, Fit Space cannot be used with Hint, Augment, or Drift data.
The User Guides have been updated, and the options will be greyed-out.
