STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-309 Verified Data - OK to distribute File created: Thu Jan 21 11:08:18 PST 2016 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: 1.8 - 3.6 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 4.0 - 6.0 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 6.0 - 10.0 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 11: 10.0 - 15.0 MeV/n 4He intensity (1/(cm^2 s sr MeV/nuc)) Column 12 - 15: 4 4He 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 309.953056 22 52 24 0 57.1141 2.2633E-01 2.1902E-02 2.1902E-03 -1.0000E+31 93 10 2 -2147483647 2015 309.953750 22 53 24 0 57.1000 2.1908E-01
