mdis2isis documentation confusing
https://isis.astrogeology.usgs.gov/Application/presentation/Tabbed/mdis2isis/mdis2isis.html has the following sentence:
"When this is detected, they are unlutted and each DN is converted to its precompressed 12-bit DN value. All output files are created in floating point DN format."
The term "unlutted" is not google-able and I don't think that the average user knows what this means.
As far as I can tell, it means un-LUT as in "look up the values in a Look-Up Table (LUT) and replace as appropriate."
