STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-043 Verified Data - OK to distribute File created: Sun Apr 26 10:36:09 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 43.010602 0 15 16 0 59.1300 1.8805E-02 8.4623E-03 1.0578E-03 -1.0000E+31 8 4 1 -2147483647 2015 43.014074 0 20 16 0 59.1350 1.1752E-02 2.1154E-03 0.0000E+00 -1.0000E+31 5 1 0 -2147483647 2015 43.017546 0 25 16 0 59.1300 2.5857E-02 4.2311E-03 1.0578E-03 -1.0000E+31 11 2 1 -2147483647 2015 43.021019 0 30 16 0 59.1313 2.1155E-02 2.1155E-03 0.0000E+00 -1.0000E+31 9 1 0 -2147483647 2015 43.024491 0 35 16 0 59.1338 2.1154E-02 2.1154E-03 1.0577E-03 -1.0000E+31 9 1 1 -2147483647 2015 43.031435 0 45 16 0 59.1288 1.4104E-02 4.2312E-03 0.0000E+00 -1.0000E+31 6 2 0 -2147483647 2015 43.034907 0 50 16 0 59.1287 2.3507E-02 4.2312E-03 1.0578E-03 -1.0000E+31 10 2 1 -2147483647 2015 43.038380 0 55 16 0 59.1289 1.6455E-02 1.0578E-02 0.0000E+00 -1.0000E+31 7 5 0 -2147483647 2015 43.059213 1 25 16 0 59.1289 1.8805E-02 4.2312E-03 0.0000E+00 -1.0000E+31 8 2 0 -2147483647 2015 43.864769 20 45 16 0 59.1062 7.5251E-02 4.2329E-03 2.1164E-03 -1.0000E+31 32 2 2 -2147483647 2015 43.868241 20 50 16 0 59.0913 7.9974E-02 8.4678E-03 0.0000E+00 -1.0000E+31 34 4 0 -2147483647 2015 43.871713 20 55 16 0 59.0926 7.2916E-02 1.0585E-02 1.0585E-03 -1.0000E+31 31 5 1 -2147483647 2015 43.875185 21 0 16 0 59.0845 7.7631E-02 1.4820E-02 3.1758E-03 -1.0000E+31 33 7 3 -2147483647 2015 43.878657 21 5 16 0 59.0900 7.5271E-02 1.0585E-02 2.1170E-03 -1.0000E+31 32 5 2 -2147483647 2015 43.882130 21 10 16 0 59.0935 7.0563E-02 1.6935E-02 0.0000E+00 -1.0000E+31 30 8 0 -2147483647 2015 43.885602 21 15 16 0 59.0914 7.0565E-02 1.0585E-02 2.1170E-03 -1.0000E+31 30 5 2 -2147483647 2015 43.889074 21 20 16 0 59.0878 7.5274E-02 1.2702E-02 1.0585E-03 -1.0000E+31 32 6 1 -2147483647 2015 43.892546 21 25 16 0 59.0787 1.0117E-01 4.2348E-03 1.0587E-03 -1.0000E+31 43 2 1 -2147483647 2015 43.896019 21 30 16 0 59.0848 7.0573E-02 6.3516E-03 3.1758E-03 -1.0000E+31 30 3 3 -2147483647 2015 43.899491 21 35 16 0 59.0911 7.2918E-02 1.0585E-02 0.0000E+00 -1.0000E+31 31 5 0 -2147483647 2015 43.902963 21 40 16 0 59.0911 6.5861E-02 1.2702E-02 0.0000E+00 -1.0000E+31 28 6 0 -2147483647 2015 43.906435 21 45 16 0 59.0899 7.5271E-02 4.2340E-03 1.0585E-03 -1.0000E+31 32 2 1 -2147483647 2015 43.913380 21 55 16 0 59.0839 8.7041E-02 1.0586E-02 1.0586E-03 -1.0000E+31 37 5 1 -2147483647
