STEREO LET LEVEL 1 combined proton data for ahead spacecraft, for 2015-012 Verified Data - OK to distribute File created: Tue Apr 7 10:36:00 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 proton intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 4.0 - 6.0 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 6.0 - 10.0 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 11: 10.0 - 15.0 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 12 - 15: 4 proton 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 12.642593 15 25 20 0 59.1406 2.1622E-01 5.7110E-02 2.5382E-02 -1.0000E+31 92 27 24 -2147483647 2015 12.646065 15 30 20 0 59.1417 1.9506E-01 7.1915E-02 1.1633E-02 -1.0000E+31 83 34 11 -2147483647 2015 12.649537 15 35 20 0 59.1405 2.0682E-01 7.4032E-02 1.5864E-02 -1.0000E+31 88 35 15 -2147483647 2015 12.653009 15 40 20 0 59.1341 1.9979E-01 6.7694E-02 2.8558E-02 -1.0000E+31 85 32 27 -2147483647 2015 12.656481 15 45 20 0 59.1417 2.2327E-01 6.9800E-02 2.1152E-02 -1.0000E+31 95 33 20 -2147483647 2015 12.659954 15 50 20 0 59.1405 2.0917E-01 9.5184E-02 1.5864E-02 -1.0000E+31 89 45 15 -2147483647 2015 12.663426 15 55 20 0 59.1391 2.2093E-01 8.2495E-02 1.0576E-02 -1.0000E+31 94 39 10 -2147483647 2015 12.666898 16 0 20 0 59.1392 2.3973E-01 9.3071E-02 1.5864E-02 -1.0000E+31 102 44 15 -2147483647 2015 12.670370 16 5 20 0 59.1406 2.4207E-01 8.2493E-02 1.6922E-02 -1.0000E+31 103 39 16 -2147483647 2015 12.677315 16 15 20 0 59.1393 2.3503E-01 7.8264E-02 1.9037E-02 -1.0000E+31 100 37 18 -2147483647 2015 12.680787 16 20 20 0 59.1404 2.4677E-01 7.4032E-02 1.4806E-02 -1.0000E+31 105 35 14 -2147483647 2015 12.684259 16 25 20 0 59.1418 2.3267E-01 5.9224E-02 2.2209E-02 -1.0000E+31 99 28 21 -2147483647 2015 12.687731 16 30 20 0 59.1354 2.7735E-01 6.9808E-02 2.7500E-02 -1.0000E+31 118 33 26 -2147483647 2015 12.691204 16 35 20 0 59.1416 2.4912E-01 7.8261E-02 2.1152E-02 -1.0000E+31 106 37 20 -2147483647 2015 12.694676 16 40 20 0 59.1441 2.4676E-01 7.1912E-02 1.4805E-02 -1.0000E+31 105 34 14 -2147483647 2015 12.698148 16 45 20 0 59.1367 2.9380E-01 6.9806E-02 2.1153E-02 -1.0000E+31 125 33 20 -2147483647 2015 12.701620 16 50 20 0 59.1430 2.6791E-01 7.4029E-02 1.5863E-02 -1.0000E+31 114 35 15 -2147483647 2015 12.705093 16 55 20 0 59.1405 1.9977E-01 6.9802E-02 2.0094E-02 -1.0000E+31 85 33 19 -2147483647 2015 12.708565 17 0 20 0 59.1393 2.4208E-01 7.8264E-02 2.2210E-02 -1.0000E+31 103 37 21 -2147483647 2015 12.712037 17 5 20 0 59.1405 1.8332E-01 6.7686E-02 2.2210E-02 -1.0000E+31 78 32 21 -2147483647 2015 12.715509 17 10 20 0 59.1354 2.3269E-01 6.3461E-02 1.7981E-02 -1.0000E+31 99 30 17 -2147483647 2015 12.718981 17 15 20 0 59.1366 1.7863E-01 7.8268E-02 2.2211E-02 -1.0000E+31 76 37 21 -2147483647 2015 12.722454 17 20 20 0 59.1405 2.1622E-01 9.3069E-02 1.9037E-02 -1.0000E+31 92 44 18 -2147483647 2015 12.725926 17 25 20 0 59.1394 2.3503E-01 1.0365E-01 2.4325E-02 -1.0000E+31 100 49 23 -2147483647
