STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-041 Verified Data - OK to distribute File created: Sun Apr 26 10:36:04 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 41.590463 14 10 16 0 59.1041 3.2923E-02 1.4816E-02 0.0000E+00 -1.0000E+31 14 7 0 -2147483647 2015 41.593935 14 15 16 0 59.1003 1.1759E-02 6.3499E-03 1.0583E-03 -1.0000E+31 5 3 1 -2147483647 2015 41.597407 14 20 16 0 59.1035 3.9979E-02 2.1165E-03 1.0583E-03 -1.0000E+31 17 1 1 -2147483647 2015 41.600880 14 25 16 0 59.0981 3.2927E-02 6.3501E-03 0.0000E+00 -1.0000E+31 14 3 0 -2147483647 2015 41.604352 14 30 16 0 59.1074 3.0570E-02 0.0000E+00 1.0582E-03 -1.0000E+31 13 0 1 -2147483647 2015 41.607824 14 35 16 0 59.0972 3.9983E-02 2.1167E-03 1.0584E-03 -1.0000E+31 17 1 1 -2147483647 2015 41.611296 14 40 16 0 59.1033 3.5276E-02 4.2331E-03 1.0583E-03 -1.0000E+31 15 2 1 -2147483647 2015 41.618241 14 50 16 0 59.1012 3.2925E-02 4.2332E-03 0.0000E+00 -1.0000E+31 14 2 0 -2147483647 2015 41.621713 14 55 16 0 59.0960 3.7632E-02 2.1168E-03 2.1168E-03 -1.0000E+31 16 1 2 -2147483647 2015 41.625185 15 0 16 0 59.0959 4.4688E-02 1.0584E-02 0.0000E+00 -1.0000E+31 19 5 0 -2147483647 2015 41.628657 15 5 16 0 59.0972 3.2927E-02 6.3502E-03 2.1167E-03 -1.0000E+31 14 3 2 -2147483647 2015 41.632130 15 10 16 0 59.0981 6.8205E-02 4.2334E-03 0.0000E+00 -1.0000E+31 29 2 0 -2147483647 2015 41.635602 15 15 16 0 59.0968 5.8799E-02 4.2335E-03 0.0000E+00 -1.0000E+31 25 2 0 -2147483647 2015 41.639074 15 20 16 0 59.0966 2.8224E-02 1.2701E-02 1.0584E-03 -1.0000E+31 12 6 1 -2147483647 2015 41.642546 15 25 16 0 59.0960 6.3504E-02 6.3504E-03 0.0000E+00 -1.0000E+31 27 3 0 -2147483647 2015 41.646019 15 30 16 0 59.0981 3.5279E-02 6.3501E-03 1.0584E-03 -1.0000E+31 15 3 1 -2147483647 2015 41.649491 15 35 16 0 59.0992 2.3519E-02 2.1167E-03 0.0000E+00 -1.0000E+31 10 1 0 -2147483647 2015 41.652963 15 40 16 0 59.0978 3.9983E-02 0.0000E+00 1.0584E-03 -1.0000E+31 17 0 1 -2147483647 2015 41.656435 15 45 16 0 59.0958 3.5280E-02 8.4672E-03 0.0000E+00 -1.0000E+31 15 4 0 -2147483647 2015 41.659907 15 50 16 0 59.1030 4.4683E-02 4.2331E-03 1.0583E-03 -1.0000E+31 19 2 1 -2147483647 2015 41.663380 15 55 16 0 59.1027 4.4683E-02 2.1165E-03 1.0583E-03 -1.0000E+31 19 1 1 -2147483647 2015 41.666852 16 0 16 0 59.1019 5.4090E-02 8.4663E-03 2.1166E-03 -1.0000E+31 23 4 2 -2147483647
