STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-013 Verified Data - OK to distribute File created: Tue Apr 7 10:36:05 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 13.347454 8 20 20 0 59.1402 4.7005E-03 2.1152E-03 0.0000E+00 -1.0000E+31 2 1 0 -2147483647 2015 13.350926 8 25 20 0 59.1430 7.0504E-03 4.2302E-03 0.0000E+00 -1.0000E+31 3 2 0 -2147483647 2015 13.354398 8 30 20 0 59.1413 2.1152E-02 0.0000E+00 0.0000E+00 -1.0000E+31 9 0 0 -2147483647 2015 13.357870 8 35 20 0 59.1401 1.4101E-02 0.0000E+00 0.0000E+00 -1.0000E+31 6 0 0 -2147483647 2015 13.361343 8 40 20 0 59.1440 1.6451E-02 6.3452E-03 0.0000E+00 -1.0000E+31 7 3 0 -2147483647 2015 13.364815 8 45 20 0 59.1402 1.1751E-02 2.1152E-03 0.0000E+00 -1.0000E+31 5 1 0 -2147483647 2015 13.368287 8 50 20 0 59.1415 1.6451E-02 4.2303E-03 0.0000E+00 -1.0000E+31 7 2 0 -2147483647 2015 13.371759 8 55 20 0 59.1404 2.3502E-03 2.1152E-03 1.0576E-03 -1.0000E+31 1 1 1 -2147483647 2015 13.378704 9 5 20 0 59.1416 1.8801E-02 0.0000E+00 1.0576E-03 -1.0000E+31 8 0 1 -2147483647 2015 13.382176 9 10 20 0 59.1428 2.3501E-02 4.2302E-03 2.1151E-03 -1.0000E+31 10 2 2 -2147483647 2015 13.385648 9 15 20 0 59.1390 2.1153E-02 2.1153E-03 0.0000E+00 -1.0000E+31 9 1 0 -2147483647 2015 13.389120 9 20 20 0 59.1415 7.0505E-03 6.3455E-03 0.0000E+00 -1.0000E+31 3 3 0 -2147483647 2015 13.392593 9 25 20 0 59.1454 1.8800E-02 4.2300E-03 0.0000E+00 -1.0000E+31 8 2 0 -2147483647 2015 13.396065 9 30 20 0 59.1377 1.8803E-02 4.2306E-03 0.0000E+00 -1.0000E+31 8 2 0 -2147483647 2015 13.399537 9 35 20 0 59.1376 9.4013E-03 4.2306E-03 0.0000E+00 -1.0000E+31 4 2 0 -2147483647 2015 13.403009 9 40 20 0 59.1402 1.6452E-02 2.1152E-03 0.0000E+00 -1.0000E+31 7 1 0 -2147483647 2015 13.406481 9 45 20 0 59.1416 1.4101E-02 6.3455E-03 0.0000E+00 -1.0000E+31 6 3 0 -2147483647 2015 13.409954 9 50 20 0 59.1415 1.4101E-02 0.0000E+00 0.0000E+00 -1.0000E+31 6 0 0 -2147483647 2015 13.413426 9 55 20 0 59.1414 2.5852E-02 0.0000E+00 0.0000E+00 -1.0000E+31 11 0 0 -2147483647 2015 13.416898 10 0 20 0 59.1390 9.4011E-03 4.2305E-03 0.0000E+00 -1.0000E+31 4 2 0 -2147483647 2015 13.420370 10 5 20 0 59.1402 1.4101E-02 4.2304E-03 2.1152E-03 -1.0000E+31 6 2 2 -2147483647 2015 13.423843 10 10 20 0 59.1428 1.4101E-02 2.1151E-03 1.0576E-03 -1.0000E+31 6 1 1 -2147483647 2015 13.427315 10 15 20 0 59.1415 1.6451E-02 0.0000E+00 1.0576E-03 -1.0000E+31 7 0 1 -2147483647
