Quality Control

saturated irradiance values were removed from the data set

data from approximately 1720 PST on May 13 1997 (day 133) 
until the end of the data set (May 15 1997) appeared unreliable 
and were removed from the data set.

Data from before day 60 in the Ed670 and Ed683 data sets appeared 
unreliable and were removed (the data indicated zero irradiance at 
these wavelengths in this period).
