STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-014 Verified Data - OK to distribute File created: Tue Apr 7 10:36:09 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: 4.0 - 6.0 MeV/n He intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 6.0 - 10.0 MeV/n He intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 10.0 - 15.0 MeV/n He intensity (1/(cm^2 s sr MeV/nuc)) Column 11 - 13: 3 He 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 14.642593 15 25 20 0 59.1211 6.3477E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 14.646065 15 30 20 0 59.1224 1.2695E-02 0.0000E+00 -1.0000E+31 6 0 -2147483647 2015 14.649537 15 35 20 0 59.1186 1.2696E-02 1.0580E-03 -1.0000E+31 6 1 -2147483647 2015 14.653009 15 40 20 0 59.1186 4.2320E-03 1.0580E-03 -1.0000E+31 2 1 -2147483647 2015 14.656481 15 45 20 0 59.1199 6.3478E-03 1.0580E-03 -1.0000E+31 3 1 -2147483647 2015 14.659954 15 50 20 0 59.1200 4.2319E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 14.663426 15 55 20 0 59.1175 6.3481E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 14.666898 16 0 20 0 59.1187 4.2320E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 14.670370 16 5 20 0 59.1200 1.0580E-02 1.0580E-03 -1.0000E+31 5 1 -2147483647 2015 14.677315 16 15 20 0 59.1172 1.4812E-02 2.1160E-03 -1.0000E+31 7 2 -2147483647 2015 14.680787 16 20 20 0 59.1200 4.2319E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 14.684259 16 25 20 0 59.1185 2.1160E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 14.687731 16 30 20 0 59.1175 8.4641E-03 3.1740E-03 -1.0000E+31 4 3 -2147483647 2015 14.691204 16 35 20 0 59.1211 1.0579E-02 0.0000E+00 -1.0000E+31 5 0 -2147483647 2015 14.694676 16 40 20 0 59.1186 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 14.698148 16 45 20 0 59.1173 8.4641E-03 1.0580E-03 -1.0000E+31 4 1 -2147483647 2015 14.701620 16 50 20 0 59.1186 6.3479E-03 2.1160E-03 -1.0000E+31 3 2 -2147483647 2015 14.705093 16 55 20 0 59.1212 4.2318E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 14.708565 17 0 20 0 59.1211 8.4636E-03 2.1159E-03 -1.0000E+31 4 2 -2147483647 2015 14.712037 17 5 20 0 59.1225 1.0579E-02 1.0579E-03 -1.0000E+31 5 1 -2147483647 2015 14.715509 17 10 20 0 59.1174 2.1160E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 14.718981 17 15 20 0 59.1175 8.4641E-03 2.1160E-03 -1.0000E+31 4 2 -2147483647 2015 14.722454 17 20 20 0 59.1198 6.3478E-03 2.1159E-03 -1.0000E+31 3 2 -2147483647 2015 14.725926 17 25 20 0 59.1248 1.0579E-02 1.0579E-03 -1.0000E+31 5 1 -2147483647
