STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-045 Verified Data - OK to distribute File created: Sun Apr 26 10:36:18 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 45.632130 15 10 16 0 59.0661 1.2707E-02 0.0000E+00 -1.0000E+31 6 0 -2147483647 2015 45.635602 15 15 16 0 59.0761 2.1175E-03 2.1175E-03 -1.0000E+31 1 2 -2147483647 2015 45.639074 15 20 16 0 59.0694 1.0589E-02 3.1766E-03 -1.0000E+31 5 3 -2147483647 2015 45.642546 15 25 16 0 59.0837 6.3517E-03 1.0586E-03 -1.0000E+31 3 1 -2147483647 2015 45.646019 15 30 16 0 59.0945 6.3505E-03 1.0584E-03 -1.0000E+31 3 1 -2147483647 2015 45.649491 15 35 16 0 59.0949 1.2701E-02 2.1168E-03 -1.0000E+31 6 2 -2147483647 2015 45.652963 15 40 16 0 59.0968 4.2335E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 45.656435 15 45 16 0 59.0853 8.4687E-03 0.0000E+00 -1.0000E+31 4 0 -2147483647 2015 45.659907 15 50 16 0 59.0912 8.4679E-03 1.0585E-03 -1.0000E+31 4 1 -2147483647 2015 45.663380 15 55 16 0 59.0902 1.0585E-02 3.1755E-03 -1.0000E+31 5 3 -2147483647 2015 45.666852 16 0 16 0 59.0850 6.3516E-03 2.1172E-03 -1.0000E+31 3 2 -2147483647
