10Min-averaging Software Version: 04
Level 1 software version: 11
Time Resolution: 10 Minutes
Note: Timestamps mark Beginning of averaging interval.
These data are binned into wider energy ranges than the raw data.
They should be useful for plotting trends or computing ratios.
Column 1: Year
Column 2: Day of year (fractional)
Column 3: Hour of day
Column 4: Minute of hour
Column 5: Second of minute
Column 6: LET Livetime (seconds)
Column 7:   4.0 -  6.0 MeV/nuc sulfur intensity (1/(cm^2 s sr MeV/nuc))"
Column 8:   6.0 - 10.0 MeV/nuc sulfur intensity (1/(cm^2 s sr MeV/nuc))"
Column 9:  10.0 - 15.0 MeV/nuc sulfur intensity (1/(cm^2 s sr MeV/nuc))"
Column 10: 15.0 - 27.0 MeV/nuc sulfur intensity (1/(cm^2 s sr MeV/nuc))"
Column 11: 27.0 - 40.0 MeV/nuc sulfur intensity (1/(cm^2 s sr MeV/nuc))"
Column 12 - 16: 5 sulfur counts, same energy ranges as above (counts/minute)"
Column 17 - 21: 5 sulfur statistical uncertainties  (1/(cm^2 s sr MeV/nuc))
Bad/missing data are filled as follows:
     -9999.9 for floating-point data
     -9999 for integer data
10-minute Averages and Uncertainties are calculated as follows:
     I = Sum(Ii)/M
     U(I) = sqrt ( Sum( Ii^2/Ni ) ) / M
     I is the hourly average intensity
     U(I) is the uncertainty in the calculated average intensity
     Ii is the intensity for minute i in one of the energy bins
     Ii^2 = Ii * Ii  (in case the notation is confusing...)
     Ni is the counts for minute i in one of the energy bins
     M is the number of good 1-minute records in the averaging interval.
