STEREO LET LEVEL 1 combined Helium data for behind spacecraft, for 2011-151 Verified Data - OK to distribute File created: Thu Mar 28 17:50:27 PDT 2013 Created by: Caltech Space Radiation Lab Level 1 software version 11 Time Resolution: 1 minute (highest LET instrument resolution) Note: Timestamps mark beginning of data accumulation 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 dynamic threshold state (0 - 3) Column 7: LET Livetime (seconds) Column 8: 4.0 - 6.0 MeV/n He intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 6.0 - 10.0 MeV/n He intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 10.0 - 15.0 MeV/n He intensity (1/(cm^2 s sr MeV/nuc)) Column 11 - 13: 3 He counts , same energy ranges as above (counts/minute) Bad/missing data are filled with -1.0E+31 for floating point, -2147483647 for integers BEGIN DATA 2011 151.000197 0 0 17 0 49.0727 2.5492E-02 1.2746E-03 -1.0000E+31 10 1 -2147483647 2011 151.000891 0 1 17 0 48.9857 3.3198E-02 1.2768E-03 -1.0000E+31 13 1 -2147483647 2011 151.001586 0 2 17 0 48.6610 1.7995E-02 0.0000E+00 -1.0000E+31 7 0 -2147483647 2011 151.002280 0 3 17 0 48.3168 2.5890E-02 0.0000E+00 -1.0000E+31 10 0 -2147483647 2011 151.002975 0 4 17 0 47.7301 2.0967E-02 1.3104E-03 -1.0000E+31 8 1 -2147483647 2011 151.003669 0 5 17 0 47.1755 2.9168E-02 0.0000E+00 -1.0000E+31 11 0 -2147483647 2011 151.004363 0 6 17 0 46.7626 2.4076E-02 6.6877E-03 -1.0000E+31 9 5 -2147483647 2011 151.005058 0 7 17 0 46.9122 1.5999E-02 1.3333E-03 -1.0000E+31 6 1 -2147483647 2011 151.005752 0 8 17 0 47.7503 3.4057E-02 1.3099E-03 -1.0000E+31 13 1 -2147483647 2011 151.006447 0 9 17 0 47.5144 2.8960E-02 2.6328E-03 -1.0000E+31 11 2 -2147483647 2011 151.007141 0 10 17 0 46.5747 1.8801E-02 0.0000E+00 -1.0000E+31 7 0 -2147483647 2011 151.007836 0 11 17 0 42.3774 3.8375E-02 5.9038E-03 -1.0000E+31 13 4 -2147483647 2011 151.008530 0 12 17 0 35.0576 3.9251E-02 5.3524E-03 -1.0000E+31 11 3 -2147483647 2011 151.009225 0 13 17 0 31.7843 4.3293E-02 3.9357E-03 -1.0000E+31 11 2 -2147483647 2011 151.009919 0 14 17 0 30.6809 3.2618E-02 0.0000E+00 -1.0000E+31 8 0 -2147483647 2011 151.010613 0 15 17 0 30.0382 4.1645E-02 4.1645E-03 -1.0000E+31 10 2 -2147483647 2011 151.011308 0 16 17 0 29.3516 4.6881E-02 0.0000E+00 -1.0000E+31 11 0 -2147483647 2011 151.012002 0 17 17 0 28.8320 3.9048E-02 2.1694E-03 -1.0000E+31 9 1 -2147483647 2011 151.012697 0 18 17 0 28.4604 4.3954E-02 6.5931E-03 -1.0000E+31 10 3 -2147483647 2011 151.013391 0 19 17 0 28.5094 5.2654E-02 4.3878E-03 -1.0000E+31 12 2 -2147483647 2011 151.014086 0 20 17 0 28.2115 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647
