STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-012 Verified Data - OK to distribute File created: Tue Apr 7 10:36:01 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 12.642593 15 25 20 0 59.1406 9.4009E-03 2.1152E-03 0.0000E+00 -1.0000E+31 4 1 0 -2147483647 2015 12.646065 15 30 20 0 59.1417 4.7003E-03 8.4606E-03 0.0000E+00 -1.0000E+31 2 4 0 -2147483647 2015 12.649537 15 35 20 0 59.1405 2.3502E-02 4.2304E-03 1.0576E-03 -1.0000E+31 10 2 1 -2147483647 2015 12.653009 15 40 20 0 59.1341 9.4019E-03 1.0577E-02 0.0000E+00 -1.0000E+31 4 5 0 -2147483647 2015 12.656481 15 45 20 0 59.1417 1.4101E-02 0.0000E+00 1.0576E-03 -1.0000E+31 6 0 1 -2147483647 2015 12.659954 15 50 20 0 59.1405 4.7004E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 12.663426 15 55 20 0 59.1391 1.1751E-02 2.1152E-03 0.0000E+00 -1.0000E+31 5 1 0 -2147483647 2015 12.666898 16 0 20 0 59.1392 1.8802E-02 0.0000E+00 0.0000E+00 -1.0000E+31 8 0 0 -2147483647 2015 12.670370 16 5 20 0 59.1406 1.4101E-02 2.1152E-03 0.0000E+00 -1.0000E+31 6 1 0 -2147483647 2015 12.677315 16 15 20 0 59.1393 1.4102E-02 4.2305E-03 0.0000E+00 -1.0000E+31 6 2 0 -2147483647 2015 12.680787 16 20 20 0 59.1404 1.1751E-02 2.1152E-03 1.0576E-03 -1.0000E+31 5 1 1 -2147483647 2015 12.684259 16 25 20 0 59.1418 1.4101E-02 2.1152E-03 1.0576E-03 -1.0000E+31 6 1 1 -2147483647 2015 12.687731 16 30 20 0 59.1354 1.4103E-02 0.0000E+00 0.0000E+00 -1.0000E+31 6 0 0 -2147483647 2015 12.691204 16 35 20 0 59.1416 1.1751E-02 0.0000E+00 0.0000E+00 -1.0000E+31 5 0 0 -2147483647 2015 12.694676 16 40 20 0 59.1441 7.0502E-03 2.1151E-03 0.0000E+00 -1.0000E+31 3 1 0 -2147483647 2015 12.698148 16 45 20 0 59.1367 9.4015E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 12.701620 16 50 20 0 59.1430 2.3501E-02 0.0000E+00 0.0000E+00 -1.0000E+31 10 0 0 -2147483647 2015 12.705093 16 55 20 0 59.1405 1.8802E-02 4.2304E-03 1.0576E-03 -1.0000E+31 8 2 1 -2147483647 2015 12.708565 17 0 20 0 59.1393 1.6452E-02 0.0000E+00 0.0000E+00 -1.0000E+31 7 0 0 -2147483647 2015 12.712037 17 5 20 0 59.1405 1.4101E-02 4.2304E-03 0.0000E+00 -1.0000E+31 6 2 0 -2147483647 2015 12.715509 17 10 20 0 59.1354 9.4017E-03 4.2308E-03 1.0577E-03 -1.0000E+31 4 2 1 -2147483647 2015 12.718981 17 15 20 0 59.1366 9.4015E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 12.722454 17 20 20 0 59.1405 4.7004E-03 4.2304E-03 0.0000E+00 -1.0000E+31 2 2 0 -2147483647 2015 12.725926 17 25 20 0 59.1394 1.4102E-02 4.2305E-03 0.0000E+00 -1.0000E+31 6 2 0 -2147483647
