STEREO LET LEVEL 1 combined Helium 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: 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 2015 62.097384 2 20 14 0 58.0681 2.8005E-02 5.3856E-03 -1.0000E+31 13 5 -2147483647 2015 62.100856 2 25 14 0 58.0683 4.0931E-02 7.5399E-03 -1.0000E+31 19 7 -2147483647 2015 62.104329 2 30 14 0 58.0076 3.0191E-02 6.4695E-03 -1.0000E+31 14 6 -2147483647 2015 62.107801 2 35 14 0 57.9344 4.3185E-02 6.4777E-03 -1.0000E+31 20 6 -2147483647 2015 62.111273 2 40 14 0 57.9250 3.6713E-02 8.6383E-03 -1.0000E+31 17 8 -2147483647 2015 62.114745 2 45 14 0 57.9394 3.0227E-02 8.6362E-03 -1.0000E+31 14 8 -2147483647 2015 62.118218 2 50 14 0 57.9687 4.1001E-02 2.1580E-03 -1.0000E+31 19 2 -2147483647 2015 62.121690 2 55 14 0 57.8816 3.2418E-02 5.4030E-03 -1.0000E+31 15 5 -2147483647 2015 62.125162 3 0 14 0 57.9255 4.1032E-02 5.3989E-03 -1.0000E+31 19 5 -2147483647 2015 62.128634 3 5 14 0 57.9494 3.6697E-02 5.3967E-03 -1.0000E+31 17 5 -2147483647 2015 62.149468 3 35 14 0 58.0162 3.8811E-02 5.3905E-03 -1.0000E+31 18 5 -2147483647 2015 62.166829 4 0 14 0 58.1714 2.1504E-02 7.5265E-03 -1.0000E+31 10 7 -2147483647
