 General information
 —----------------------------------
-L1 data are intended for QA/QC. If you are a rogue analyst, beware!
+L1 data are close to raw data, although they have been units-transformed and 
+have a single out-of-instrument-bounds flag applied. True duplicates are removed 
+but otherwise these data are not filtered, and have not been subject to any algorithmic
+or human QA/QC. Any use of these data for science analyses should be done with care.
