STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-040 Verified Data - OK to distribute File created: Sun Apr 26 10:36:00 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 40.521019 12 30 16 0 59.1310 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 40.524491 12 35 16 0 59.1348 0.0000E+00 1.0577E-03 -1.0000E+31 0 1 -2147483647 2015 40.527963 12 40 16 0 59.1324 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 40.531435 12 45 16 0 59.1336 0.0000E+00 2.1154E-03 -1.0000E+31 0 2 -2147483647 2015 40.534907 12 50 16 0 59.1333 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 40.538380 12 55 16 0 59.1373 0.0000E+00 1.0577E-03 -1.0000E+31 0 1 -2147483647 2015 40.545324 13 5 16 0 59.1361 4.2307E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 40.548796 13 10 16 0 59.1336 6.3463E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 40.552269 13 15 16 0 59.1372 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 40.614769 14 45 16 0 59.1394 2.1152E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 40.618241 14 50 16 0 59.1382 0.0000E+00 1.0576E-03 -1.0000E+31 0 1 -2147483647 2015 40.621713 14 55 16 0 59.1367 4.2307E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647
