STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-034 Verified Data - OK to distribute File created: Sun Apr 26 10:35:26 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 34.149502 3 35 17 0 59.1533 2.1147E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 34.152975 3 40 17 0 59.1520 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 34.156447 3 45 17 0 59.1494 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 34.159919 3 50 17 0 59.1507 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 34.163391 3 55 17 0 59.1507 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 34.166863 4 0 17 0 59.1481 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 34.170336 4 5 17 0 59.1520 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 34.173808 4 10 17 0 59.1482 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 34.177280 4 15 17 0 59.1469 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 34.180752 4 20 17 0 59.1533 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 34.184225 4 25 17 0 59.1507 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647
