STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-060 Verified Data - OK to distribute File created: Mon May 25 10:34:19 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 60.573079 13 45 14 0 57.9671 4.3160E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 60.576551 13 50 14 0 57.8194 8.6541E-03 2.1635E-03 -1.0000E+31 4 2 -2147483647 2015 60.580023 13 55 14 0 57.9084 4.3204E-03 1.0801E-03 -1.0000E+31 2 1 -2147483647 2015 60.583495 14 0 14 0 57.9036 8.6415E-03 2.1604E-03 -1.0000E+31 4 2 -2147483647 2015 60.586968 14 5 14 0 57.8807 4.3225E-03 1.0806E-03 -1.0000E+31 2 1 -2147483647 2015 60.590440 14 10 14 0 57.8446 4.3252E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 60.593912 14 15 14 0 57.8548 2.1622E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 60.597384 14 20 14 0 57.8743 2.1615E-03 2.1615E-03 -1.0000E+31 1 2 -2147483647 2015 60.600856 14 25 14 0 57.9424 6.4768E-03 4.3179E-03 -1.0000E+31 3 4 -2147483647 2015 60.604329 14 30 14 0 57.6454 6.5102E-03 2.1701E-03 -1.0000E+31 3 2 -2147483647 2015 60.649468 15 35 14 0 57.7151 1.0837E-02 2.1674E-03 -1.0000E+31 5 2 -2147483647 2015 60.656412 15 45 14 0 57.5916 1.5205E-02 1.0860E-03 -1.0000E+31 7 1 -2147483647 2015 60.663356 15 55 14 0 57.7156 6.5023E-03 3.2511E-03 -1.0000E+31 3 3 -2147483647 2015 60.666829 16 0 14 0 57.6980 2.1681E-03 4.3362E-03 -1.0000E+31 1 4 -2147483647
