STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-035 Verified Data - OK to distribute File created: Sun Apr 26 10:35:32 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 35.569641 13 40 17 0 59.1517 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.573113 13 45 17 0 59.1491 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.576586 13 50 17 0 59.1530 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.580058 13 55 17 0 59.1542 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.583530 14 0 17 0 59.1529 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.587002 14 5 17 0 59.1554 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.590475 14 10 17 0 59.1529 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.593947 14 15 17 0 59.1516 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.597419 14 20 17 0 59.1529 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.600891 14 25 17 0 59.1555 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 35.604363 14 30 17 0 59.1503 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647
