STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-055 Verified Data - OK to distribute File created: Sun Apr 26 10:36:53 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: 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 2015 55.198090 4 45 15 1 52.7618 2.6356E+00 1.6279E-01 5.8138E-03 -1.0000E+31 204 14 1 -2147483647 2015 55.201563 4 50 15 1 52.0387 2.8425E+00 1.2968E-01 1.7684E-02 -1.0000E+31 217 11 3 -2147483647 2015 55.205035 4 55 15 1 52.5017 2.7525E+00 7.0112E-02 0.0000E+00 -1.0000E+31 212 6 0 -2147483647 2015 55.208507 5 0 15 1 54.2090 2.1377E+00 9.0538E-02 5.6586E-03 -1.0000E+31 170 8 1 -2147483647 2015 55.211979 5 5 15 1 54.8034 1.8284E+00 3.3583E-02 5.5972E-03 -1.0000E+31 147 3 1 -2147483647 2015 55.878646 21 5 15 1 57.0518 7.2884E-01 4.3013E-02 0.0000E+00 -1.0000E+31 61 4 0 -2147483647 2015 55.882118 21 10 15 0 57.0791 1.1688E-01 4.3832E-03 0.0000E+00 -1.0000E+31 48 2 0 -2147483647 2015 55.885590 21 15 15 0 57.0948 1.5580E-01 4.3820E-03 1.0955E-03 -1.0000E+31 64 2 1 -2147483647 2015 55.889063 21 20 15 0 57.1033 1.5821E-01 4.3813E-03 0.0000E+00 -1.0000E+31 65 2 0 -2147483647 2015 55.896007 21 30 15 0 57.1330 1.3624E-01 1.0948E-02 0.0000E+00 -1.0000E+31 56 5 0 -2147483647 2015 55.899479 21 35 15 0 57.1637 1.4346E-01 6.5650E-03 0.0000E+00 -1.0000E+31 59 3 0 -2147483647
