STEREO LET Level 1 Combined Helium intensities for ahead spacecraft, for 2006 Verified Data - OK to distribute File Created: Tue Apr 23 14:59:12 PDT 2013 Created by: Caltech Space Radiation Lab Daily-averaging Software Version: 04 Level 1 software version: 11 Time Resolution: 1 day 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 He intensity (1/(cm^2 s sr MeV/nuc)) Column 8: 6.0 - 10.0 MeV/nuc He intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 10.0 - 15.0 MeV/nuc He intensity (1/(cm^2 s sr MeV/nuc)) Column 10 - 12: 3 He counts , same energy ranges as above (counts/minute) Column 13 - 15: 3 He 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 daily Averages and Uncertainties are calculated as follows: I = Sum(Ii)/M U(I) = sqrt ( Sum( Ii^2/Ni ) ) / M I is the daily 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.
