MAO/PGH/PVC/SGP/SASHE/C1 - Reprocess: Stray light contamination at extreme wavelengths

The irradiance measurements at near the limits of the spectrometer wavelength ranges are 
subject to contamination from stray light within the spectrometer itself. This affects not 
only the basic measurement, but also can affect the calibration such that reported 
values may be either higher or lower than actual. Typically, this yields a high bias for 
measurements at the low wavelength limit and a low bias at the high wavelength limit. This 
causes opposite effects for AOD with a low bias at low wavelength and a high bias for high 
wavelengths.
