STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-015 Verified Data - OK to distribute File created: Tue Apr 7 10:36:14 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 15.666898 16 0 20 0 59.1266 2.5858E-02 0.0000E+00 2.1157E-03 -1.0000E+31 11 0 2 -2147483647 2015 15.670370 16 5 20 0 59.1268 4.7015E-02 1.0578E-02 1.0578E-03 -1.0000E+31 20 5 1 -2147483647 2015 15.673843 16 10 20 0 59.1255 3.9964E-02 6.3472E-03 1.0579E-03 -1.0000E+31 17 3 1 -2147483647 2015 15.677315 16 15 20 0 59.1256 2.8210E-02 1.2694E-02 2.1157E-03 -1.0000E+31 12 6 2 -2147483647 2015 15.680787 16 20 20 0 59.1244 2.8210E-02 4.2315E-03 1.0579E-03 -1.0000E+31 12 2 1 -2147483647 2015 15.684259 16 25 20 0 59.1231 2.1158E-02 2.1158E-03 0.0000E+00 -1.0000E+31 9 1 0 -2147483647 2015 15.687731 16 30 20 0 59.1205 1.8808E-02 0.0000E+00 0.0000E+00 -1.0000E+31 8 0 0 -2147483647 2015 15.694676 16 40 20 0 59.1259 4.2314E-02 8.4629E-03 0.0000E+00 -1.0000E+31 18 4 0 -2147483647 2015 15.698148 16 45 20 0 59.1220 1.4106E-02 8.4634E-03 0.0000E+00 -1.0000E+31 6 4 0 -2147483647 2015 15.701620 16 50 20 0 59.1256 2.5859E-02 2.1157E-03 0.0000E+00 -1.0000E+31 11 1 0 -2147483647 2015 15.705093 16 55 20 0 59.1219 3.9966E-02 2.1159E-03 1.0579E-03 -1.0000E+31 17 1 1 -2147483647 2015 15.708565 17 0 20 0 59.1255 2.3508E-02 8.4629E-03 0.0000E+00 -1.0000E+31 10 4 0 -2147483647 2015 15.712037 17 5 20 0 59.1243 4.7017E-02 8.4631E-03 3.1737E-03 -1.0000E+31 20 4 3 -2147483647 2015 15.715509 17 10 20 0 59.1218 2.8212E-02 6.3476E-03 1.0579E-03 -1.0000E+31 12 3 1 -2147483647 2015 15.718981 17 15 20 0 59.1256 2.3508E-02 6.3472E-03 0.0000E+00 -1.0000E+31 10 3 0 -2147483647 2015 15.722454 17 20 20 0 59.1244 2.5859E-02 8.4631E-03 0.0000E+00 -1.0000E+31 11 4 0 -2147483647
