STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-018 Verified Data - OK to distribute File created: Tue Apr 7 10:36:29 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 18.000231 0 0 20 0 59.1512 9.3992E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 18.003704 0 5 20 0 59.1473 2.3499E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 18.007176 0 10 20 0 59.1497 4.6997E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 18.010648 0 15 20 0 59.1473 4.6999E-03 0.0000E+00 1.0575E-03 -1.0000E+31 2 0 1 -2147483647 2015 18.014120 0 20 20 0 59.1498 1.1749E-02 4.2297E-03 0.0000E+00 -1.0000E+31 5 2 0 -2147483647 2015 18.017593 0 25 20 0 59.1459 2.3500E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 18.021065 0 30 20 0 59.1434 4.7002E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 18.024537 0 35 20 0 59.1485 4.6998E-03 4.2298E-03 0.0000E+00 -1.0000E+31 2 2 0 -2147483647 2015 18.225926 5 25 20 0 59.1436 7.0503E-03 6.3453E-03 0.0000E+00 -1.0000E+31 3 3 0 -2147483647 2015 18.229398 5 30 20 0 59.1435 1.1750E-02 2.1151E-03 0.0000E+00 -1.0000E+31 5 1 0 -2147483647 2015 18.232870 5 35 20 0 59.1487 7.0497E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 18.236343 5 40 20 0 59.1462 9.4000E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 18.239815 5 45 20 0 59.1436 9.4004E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 18.243287 5 50 20 0 59.1473 9.3998E-03 0.0000E+00 1.0575E-03 -1.0000E+31 4 0 1 -2147483647 2015 18.246759 5 55 20 0 59.1486 2.3499E-03 4.2298E-03 1.0575E-03 -1.0000E+31 1 2 1 -2147483647 2015 18.250231 6 0 20 0 59.1460 4.7000E-03 0.0000E+00 1.0575E-03 -1.0000E+31 2 0 1 -2147483647 2015 18.253704 6 5 20 0 59.1448 0.0000E+00 0.0000E+00 1.0575E-03 -1.0000E+31 0 0 1 -2147483647 2015 18.260648 6 15 20 0 59.1450 7.0501E-03 2.1150E-03 0.0000E+00 -1.0000E+31 3 1 0 -2147483647 2015 18.264120 6 20 20 0 59.1436 2.3501E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 18.267593 6 25 20 0 59.1463 9.4000E-03 2.1150E-03 1.0575E-03 -1.0000E+31 4 1 1 -2147483647 2015 18.271065 6 30 20 0 59.1462 4.7000E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 18.274537 6 35 20 0 59.1474 2.3499E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 18.278009 6 40 20 0 59.1461 7.0500E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 18.281481 6 45 20 0 59.1474 4.6999E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 18.284954 6 50 20 0 59.1461 7.0500E-03 2.1150E-03 0.0000E+00 -1.0000E+31 3 1 0 -2147483647 2015 18.288426 6 55 20 0 59.1462 7.0500E-03 2.1150E-03 1.0575E-03 -1.0000E+31 3 1 1 -2147483647 2015 18.291898 7 0 20 0 59.1473 7.0498E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 18.295370 7 5 20 0 59.1461 9.4000E-03 2.1150E-03 0.0000E+00 -1.0000E+31 4 1 0 -2147483647 2015 18.298843 7 10 20 0 59.1461 2.3500E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 18.302315 7 15 20 0 59.1422 9.4006E-03 2.1151E-03 0.0000E+00 -1.0000E+31 4 1 0 -2147483647 2015 18.305787 7 20 20 0 59.1461 2.3500E-03 2.1150E-03 1.0575E-03 -1.0000E+31 1 1 1 -2147483647 2015 18.309259 7 25 20 0 59.1474 9.3998E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 18.312731 7 30 20 0 59.1461 4.7000E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 18.316204 7 35 20 0 59.1448 2.3500E-03 4.2301E-03 0.0000E+00 -1.0000E+31 1 2 0 -2147483647 2015 18.319676 7 40 20 0 59.1448 2.3500E-03 0.0000E+00 1.0575E-03 -1.0000E+31 1 0 1 -2147483647 2015 18.323148 7 45 20 0 59.1448 4.7001E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 18.819676 19 40 20 0 59.1465 9.3999E-03 2.1150E-03 1.0575E-03 -1.0000E+31 4 1 1 -2147483647 2015 18.823148 19 45 20 0 59.1439 4.7002E-03 2.1151E-03 1.0575E-03 -1.0000E+31 2 1 1 -2147483647 2015 18.826620 19 50 20 0 59.1426 4.7003E-03 0.0000E+00 1.0576E-03 -1.0000E+31 2 0 1 -2147483647 2015 18.830093 19 55 20 0 59.1427 4.7003E-03 0.0000E+00 1.0576E-03 -1.0000E+31 2 0 1 -2147483647 2015 18.833565 20 0 20 0 59.1427 1.1751E-02 2.1151E-03 0.0000E+00 -1.0000E+31 5 1 0 -2147483647 2015 18.837037 20 5 20 0 59.1440 2.3501E-03 2.1151E-03 0.0000E+00 -1.0000E+31 1 1 0 -2147483647 2015 18.840509 20 10 20 0 59.1389 1.6452E-02 2.1153E-03 0.0000E+00 -1.0000E+31 7 1 0 -2147483647 2015 18.847454 20 20 20 0 59.1440 1.4100E-02 0.0000E+00 1.0575E-03 -1.0000E+31 6 0 1 -2147483647 2015 18.850926 20 25 20 0 59.1427 0.0000E+00 4.2302E-03 0.0000E+00 -1.0000E+31 0 2 0 -2147483647 2015 18.854398 20 30 20 0 59.1427 7.0504E-03 4.2302E-03 0.0000E+00 -1.0000E+31 3 2 0 -2147483647 2015 18.857870 20 35 20 0 59.1415 7.0505E-03 4.2303E-03 0.0000E+00 -1.0000E+31 3 2 0 -2147483647 2015 18.861343 20 40 20 0 59.1441 7.0502E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 18.864815 20 45 20 0 59.1415 0.0000E+00 4.2303E-03 1.0576E-03 -1.0000E+31 0 2 1 -2147483647
