STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2014-253 Verified Data - OK to distribute File created: Mon Dec 1 11:23:27 PST 2014 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 2014 253.000405 0 0 35 0 59.1198 2.1159E-03 3.1739E-03 -1.0000E+31 1 3 -2147483647 2014 253.001100 0 1 35 0 59.1224 0.0000E+00 2.1158E-03 -1.0000E+31 0 2 -2147483647 2014 253.001794 0 2 35 0 59.1224 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2014 253.002488 0 3 35 0 59.1199 2.1159E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2014 253.003183 0 4 35 0 59.1199 4.2319E-03 1.0580E-03 -1.0000E+31 2 1 -2147483647 2014 253.003877 0 5 35 0 59.1184 0.0000E+00 1.0580E-03 -1.0000E+31 0 1 -2147483647 2014 253.004572 0 6 35 0 59.1210 2.1159E-03 1.0579E-03 -1.0000E+31 1 1 -2147483647 2014 253.005266 0 7 35 0 59.1199 0.0000E+00 1.0580E-03 -1.0000E+31 0 1 -2147483647 2014 253.005961 0 8 35 0 59.1249 0.0000E+00 1.0579E-03 -1.0000E+31 0 1 -2147483647 2014 253.006655 0 9 35 0 59.1197 0.0000E+00 2.1159E-03 -1.0000E+31 0 2 -2147483647 2014 253.007350 0 10 35 0 59.1209 4.2318E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2014 253.008044 0 11 35 0 59.1211 2.1159E-03 1.0579E-03 -1.0000E+31 1 1 -2147483647 2014 253.008738 0 12 35 0 59.1197 6.3478E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2014 253.009433 0 13 35 0 59.1235 6.3474E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2014 253.010127 0 14 35 0 59.1211 4.2318E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2014 253.010822 0 15 35 0 59.1224 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2014 253.011516 0 16 35 0 59.1223 2.1158E-03 1.0579E-03 -1.0000E+31 1 1 -2147483647 2014 253.012211 0 17 35 0 59.1160 2.1161E-03 1.0580E-03 -1.0000E+31 1 1 -2147483647 2014 253.012905 0 18 35 0 59.1223 2.1158E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2014 253.013600 0 19 35 0 59.1185 2.1160E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2014 253.014294 0 20 35 0 59.1198 2.1159E-03 2.1159E-03 -1.0000E+31 1 2 -2147483647
