STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-062 Verified Data - OK to distribute File created: Mon May 25 10:34:24 PDT 2015 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: 1.8 - 3.6 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 4.0 - 6.0 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 6.0 - 10.0 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 11: 10.0 - 15.0 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 12 - 15: 4 4He 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 2015 62.097384 2 20 14 0 58.0681 3.6144E-01 2.8005E-02 5.3856E-03 -1.0000E+31 151 13 5 -2147483647 2015 62.100856 2 25 14 0 58.0683 3.3032E-01 4.0931E-02 7.5399E-03 -1.0000E+31 138 19 7 -2147483647 2015 62.104329 2 30 14 0 58.0076 3.4504E-01 3.0191E-02 6.4695E-03 -1.0000E+31 144 14 6 -2147483647 2015 62.107801 2 35 14 0 57.9344 3.5267E-01 4.3185E-02 5.3981E-03 -1.0000E+31 147 20 5 -2147483647 2015 62.111273 2 40 14 0 57.9250 4.3911E-01 3.4553E-02 7.5585E-03 -1.0000E+31 183 16 7 -2147483647 2015 62.114745 2 45 14 0 57.9394 3.6944E-01 3.0227E-02 8.6362E-03 -1.0000E+31 154 14 8 -2147483647 2015 62.118218 2 50 14 0 57.9687 3.6206E-01 3.8843E-02 2.1580E-03 -1.0000E+31 151 18 2 -2147483647 2015 62.121690 2 55 14 0 57.8816 4.1783E-01 3.0257E-02 5.4030E-03 -1.0000E+31 174 14 5 -2147483647 2015 62.125162 3 0 14 0 57.9255 3.9592E-01 4.1032E-02 5.3989E-03 -1.0000E+31 165 19 5 -2147483647 2015 62.128634 3 5 14 0 57.9494 3.9576E-01 3.4539E-02 4.3173E-03 -1.0000E+31 165 16 4 -2147483647 2015 62.149468 3 35 14 0 58.0162 3.2822E-01 3.8811E-02 5.3905E-03 -1.0000E+31 137 18 5 -2147483647 2015 62.166829 4 0 14 0 58.1714 3.0584E-01 2.1504E-02 7.5265E-03 -1.0000E+31 128 10 7 -2147483647
