STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-063 Verified Data - OK to distribute File created: Mon May 25 10:34:28 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 63.198079 4 45 14 0 58.9623 6.3648E-03 4.2432E-03 -1.0000E+31 3 4 -2147483647 2015 63.201551 4 50 14 0 58.9430 2.1223E-03 2.1223E-03 -1.0000E+31 1 2 -2147483647 2015 63.205023 4 55 14 0 58.9394 1.9102E-02 5.3060E-03 -1.0000E+31 9 5 -2147483647 2015 63.208495 5 0 14 0 58.9485 1.0610E-02 4.2442E-03 -1.0000E+31 5 4 -2147483647 2015 63.211968 5 5 14 0 58.9469 1.0611E-02 3.1832E-03 -1.0000E+31 5 3 -2147483647 2015 63.215440 5 10 14 0 58.9544 1.0609E-02 2.1219E-03 -1.0000E+31 5 2 -2147483647 2015 63.218912 5 15 14 0 58.9559 6.3655E-03 3.1827E-03 -1.0000E+31 3 3 -2147483647 2015 63.222384 5 20 14 0 58.9511 4.2440E-03 2.1220E-03 -1.0000E+31 2 2 -2147483647 2015 63.225856 5 25 14 0 58.9550 6.3656E-03 4.2437E-03 -1.0000E+31 3 4 -2147483647 2015 63.229329 5 30 14 0 58.9499 1.0610E-02 4.2441E-03 -1.0000E+31 5 4 -2147483647 2015 63.253634 6 5 14 0 58.9373 6.3675E-03 2.1225E-03 -1.0000E+31 3 2 -2147483647
