STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-051 Verified Data - OK to distribute File created: Sun Apr 26 10:36:40 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 51.590463 14 10 16 0 59.1492 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.593935 14 15 16 0 59.1493 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.597407 14 20 16 0 59.1543 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.600880 14 25 16 0 59.1518 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.604352 14 30 16 0 59.1518 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.607824 14 35 16 0 59.1518 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.611296 14 40 16 0 59.1492 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.614769 14 45 16 0 59.1517 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.618241 14 50 16 0 59.1543 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.621713 14 55 16 0 59.1518 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 51.663380 15 55 16 0 59.1518 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647
