STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2014-245 Verified Data - OK to distribute File created: Mon Dec 1 11:22:05 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: 1.8 - 3.6 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 4.0 - 6.0 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 6.0 - 10.0 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 11: 10.0 - 15.0 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 12 - 15: 4 4He 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 245.363600 8 43 35 3 54.1761 2.7729E+01 5.1796E+00 2.5898E+00 -1.0000E+31 106 22 22 -2147483647 2014 245.364294 8 44 35 3 54.1859 2.3278E+01 7.2972E+00 2.5893E+00 -1.0000E+31 89 31 22 -2147483647 2014 245.364988 8 45 35 3 54.1895 2.6415E+01 7.2968E+00 2.0007E+00 -1.0000E+31 101 31 17 -2147483647 2014 245.365683 8 46 35 3 54.2018 2.3794E+01 5.4125E+00 3.6476E+00 -1.0000E+31 91 23 31 -2147483647 2014 245.367072 8 48 35 3 54.2232 2.9273E+01 5.8808E+00 3.0580E+00 -1.0000E+31 112 25 26 -2147483647 2014 245.367766 8 49 35 3 54.2202 2.1434E+01 6.3517E+00 1.9996E+00 -1.0000E+31 82 27 17 -2147483647 2014 245.368461 8 50 35 3 54.2257 2.7704E+01 6.5862E+00 1.8818E+00 -1.0000E+31 106 28 16 -2147483647 2014 245.369850 8 52 35 3 54.2664 2.2982E+01 5.4061E+00 2.3505E+00 -1.0000E+31 88 23 20 -2147483647 2014 245.370544 8 53 35 3 54.2936 2.4798E+01 5.1684E+00 2.7017E+00 -1.0000E+31 95 22 23 -2147483647
