Column assignment of Version 2 spectra:

Column 1:	Wavelength in nm

Column 2:	Measured, corrected global spectral irradiance in uW/(cm2 nm)

Column 3:	1/cosine correction (The product of column 2 and 3 are 
		cosine-uncorrected measurements)

Column 4:	Modeled clear-sky global spectral irradiance in uW/(cm2 nm)

Column 5:	Contribution of the direct beam to the modeled clear sky 
		irradiance in %. (0 means that all incoming radiation is 
		diffuse; 100 means that all incoming radiation is direct).

Column 6:	Modeled global spectral irradiance considering clouds in 
		uW/(cm2 nm). 
		Note that ozone was set to a constant value of 300 DU. 
		No model values are given for wavelengths below 340 nm. 
		"Cloud model" spectra do not take the sphericity of the 
		Earth into account. Model spectra for solar zenith angles 
		larger than 75 degrees may underestimate the true spectrum 
		significantly.

Column 7:	Contribution of the direct beam to the modeled "cloud" 
		irradiance in %. (0 means that all incoming radiation is 
		diffuse; 100 meas that all incoming radiation is direct).

Column 8:	Time in UT in the format hours . fraction of hours

Column 9:	Solar zenith angle

Column 10:	Solar azimuth angle

Column 11:	Azimuth-error-corrected TSI measurements in Volt. 
		(TSI stands for Total Scene Irradiance and refers to a 
		filtered photodiode integral to the SUV-100 spectroradiometer. 
		The sensor is sensitive between 330 and 380 nm. Measurements 
		of the sensor can be used to estimate the variation of 
		radiation levels during the period of a spectral scans).

Column 12:	1/(TSI cosine correction) (The product of column 11 and 12 
		are azimuth-uncorrected TSI measurements).
