value 10 -- % solar zenith >= 75 and < 85 degrees
value 11 -- % missing input
value 12 -- % internal constant used in place of
climatological data for at least one atmospheric
constant
value 13 -- % correction out of bounds, pixels constrained to
extreme allowable value
value 14 -- % L1B data faulty
value 15 -- % not processed due to deep ocean or clouds
