STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-044 Verified Data - OK to distribute File created: Sun Apr 26 10:36:14 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 44.590463 14 10 16 0 59.1251 6.3472E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 44.593935 14 15 16 0 59.1290 2.1156E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 44.597407 14 20 16 0 59.1277 4.2313E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 44.600880 14 25 16 0 59.1290 2.1156E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 44.604352 14 30 16 0 59.1290 4.2312E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 44.607824 14 35 16 0 59.1182 2.1160E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 44.611296 14 40 16 0 59.1267 8.4628E-03 0.0000E+00 -1.0000E+31 4 0 -2147483647 2015 44.614769 14 45 16 0 59.1304 2.1156E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 44.618241 14 50 16 0 59.1254 0.0000E+00 2.1157E-03 -1.0000E+31 0 2 -2147483647 2015 44.621713 14 55 16 0 59.1266 2.1157E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647
