STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-046 Verified Data - OK to distribute File created: Sun Apr 26 10:36:22 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 46.632130 15 10 16 0 59.1357 2.1154E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 46.635602 15 15 16 0 59.1357 4.2307E-03 1.0577E-03 -1.0000E+31 2 1 -2147483647 2015 46.639074 15 20 16 0 59.1382 2.1153E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 46.642546 15 25 16 0 59.1406 6.3456E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 46.646019 15 30 16 0 59.1332 2.1155E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 46.649491 15 35 16 0 59.1384 0.0000E+00 1.0576E-03 -1.0000E+31 0 1 -2147483647 2015 46.652963 15 40 16 0 59.1332 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 46.656435 15 45 16 0 59.1370 6.3460E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 46.659907 15 50 16 0 59.1396 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 46.663380 15 55 16 0 59.1371 2.1153E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 46.666852 16 0 16 0 59.1396 2.1152E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 46.670324 16 5 16 0 59.1396 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 46.711991 17 5 16 0 59.1391 2.1152E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647
