STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-067 Verified Data - OK to distribute File created: Mon May 25 10:34:45 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 67.010567 0 15 13 0 54.4130 1.6348E+00 2.0461E-01 3.9083E-02 -1.0000E+31 640 89 34 -2147483647 2015 67.305706 7 20 13 0 55.4981 1.4877E+00 2.4343E-01 2.4794E-02 -1.0000E+31 594 108 22 -2147483647 2015 67.309178 7 25 13 0 55.5294 1.4142E+00 1.6896E-01 4.0550E-02 -1.0000E+31 565 75 36 -2147483647 2015 67.312650 7 30 13 0 55.4123 1.4573E+00 2.0092E-01 2.5961E-02 -1.0000E+31 581 89 23 -2147483647 2015 67.316123 7 35 13 0 55.3587 1.4362E+00 1.9885E-01 3.6155E-02 -1.0000E+31 572 88 32 -2147483647 2015 67.319595 7 40 13 0 55.3317 1.2736E+00 2.2156E-01 2.2608E-02 -1.0000E+31 507 98 20 -2147483647 2015 67.323067 7 45 13 0 55.6593 1.5008E+00 1.8879E-01 3.2589E-02 -1.0000E+31 601 84 29 -2147483647 2015 67.326539 7 50 13 0 55.3363 1.4895E+00 2.0798E-01 3.3909E-02 -1.0000E+31 593 92 30 -2147483647 2015 67.330012 7 55 13 0 55.2233 1.4925E+00 1.9028E-01 3.7376E-02 -1.0000E+31 593 84 33 -2147483647 2015 67.333484 8 0 13 0 55.2481 1.4566E+00 2.1737E-01 3.0567E-02 -1.0000E+31 579 96 27 -2147483647 2015 67.340428 8 10 13 0 55.2711 1.4208E+00 2.0369E-01 3.6212E-02 -1.0000E+31 565 90 32 -2147483647 2015 67.343900 8 15 13 0 55.2963 1.4328E+00 2.2622E-01 4.1852E-02 -1.0000E+31 570 100 37 -2147483647 2015 67.347373 8 20 13 0 55.3714 1.3630E+00 2.0107E-01 3.5017E-02 -1.0000E+31 543 89 31 -2147483647 2015 67.350845 8 25 13 0 55.4142 1.3469E+00 2.3026E-01 3.1604E-02 -1.0000E+31 537 102 28 -2147483647 2015 67.354317 8 30 13 0 55.6560 1.3036E+00 2.0229E-01 3.5962E-02 -1.0000E+31 522 90 32 -2147483647 2015 67.357789 8 35 13 0 55.7524 1.3363E+00 2.1091E-01 3.1412E-02 -1.0000E+31 536 94 28 -2147483647 2015 67.361262 8 40 13 0 55.7326 1.2420E+00 2.2894E-01 2.8057E-02 -1.0000E+31 498 102 25 -2147483647 2015 67.364734 8 45 13 0 55.7309 1.2794E+00 1.7732E-01 4.2647E-02 -1.0000E+31 513 79 38 -2147483647 2015 67.368206 8 50 13 0 55.7490 1.3563E+00 1.9970E-01 2.5805E-02 -1.0000E+31 544 89 23 -2147483647 2015 67.371678 8 55 13 0 55.8014 1.3949E+00 1.7710E-01 2.8022E-02 -1.0000E+31 560 79 25 -2147483647 2015 67.375150 9 0 13 0 55.7969 1.3352E+00 1.8160E-01 3.3629E-02 -1.0000E+31 536 81 30 -2147483647 2015 67.378623 9 5 13 0 55.8299 1.3917E+00 1.7925E-01 2.6887E-02 -1.0000E+31 559 80 24 -2147483647 2015 67.382095 9 10 13 0 55.8578 1.3984E+00 1.7692E-01 2.3515E-02 -1.0000E+31 562 79 21 -2147483647 2015 67.385567 9 15 13 0 55.9474 1.2099E+00 1.7440E-01 2.3477E-02 -1.0000E+31 487 78 21 -2147483647 2015 67.389039 9 20 13 0 55.9316 1.2425E+00 1.7445E-01 2.7957E-02 -1.0000E+31 500 78 25 -2147483647 2015 67.392512 9 25 13 0 56.0232 1.2603E+00 1.6970E-01 3.7959E-02 -1.0000E+31 508 76 34 -2147483647 2015 67.395984 9 30 13 0 55.9811 1.3407E+00 1.6089E-01 3.2401E-02 -1.0000E+31 540 72 29 -2147483647 2015 67.399456 9 35 13 0 55.9661 1.1871E+00 1.6540E-01 3.0175E-02 -1.0000E+31 478 74 27 -2147483647 2015 67.402928 9 40 13 0 56.0726 1.2022E+00 2.0971E-01 2.7887E-02 -1.0000E+31 485 94 25 -2147483647 2015 67.406400 9 45 13 0 56.1304 1.1465E+00 1.4709E-01 2.4515E-02 -1.0000E+31 463 66 22 -2147483647 2015 67.409873 9 50 13 0 56.2257 1.0753E+00 1.4684E-01 3.0035E-02 -1.0000E+31 435 66 27 -2147483647 2015 67.413345 9 55 13 0 56.2753 1.1189E+00 1.7116E-01 2.5563E-02 -1.0000E+31 453 77 23 -2147483647 2015 67.416817 10 0 13 0 56.2356 1.1419E+00 1.8018E-01 2.4469E-02 -1.0000E+31 462 81 22 -2147483647 2015 67.420289 10 5 13 0 56.2220 1.1891E+00 1.6020E-01 3.1150E-02 -1.0000E+31 481 72 28 -2147483647 2015 67.423762 10 10 13 0 56.1792 1.1381E+00 1.6478E-01 2.4494E-02 -1.0000E+31 460 74 22 -2147483647 2015 67.427234 10 15 13 0 56.3599 1.1048E+00 1.7756E-01 3.7732E-02 -1.0000E+31 448 80 34 -2147483647
