STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-064 Verified Data - OK to distribute File created: Mon May 25 10:34:32 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: 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 64.541829 13 0 14 0 59.0433 2.1187E-02 0.0000E+00 0.0000E+00 -1.0000E+31 9 0 0 -2147483647 2015 64.545301 13 5 14 0 59.0458 9.4159E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 64.548773 13 10 14 0 59.0422 1.1771E-02 2.1187E-03 0.0000E+00 -1.0000E+31 5 1 0 -2147483647 2015 64.552245 13 15 14 0 59.0446 7.0621E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 64.555718 13 20 14 0 59.0447 1.1770E-02 0.0000E+00 0.0000E+00 -1.0000E+31 5 0 0 -2147483647 2015 64.559190 13 25 14 0 59.0457 1.4124E-02 0.0000E+00 0.0000E+00 -1.0000E+31 6 0 0 -2147483647 2015 64.562662 13 30 14 0 59.0505 4.7076E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 64.566134 13 35 14 0 59.0469 9.4158E-03 4.2371E-03 0.0000E+00 -1.0000E+31 4 2 0 -2147483647 2015 64.569606 13 40 14 0 59.0430 9.4164E-03 2.1187E-03 0.0000E+00 -1.0000E+31 4 1 0 -2147483647 2015 64.573079 13 45 14 0 59.0492 1.4123E-02 0.0000E+00 0.0000E+00 -1.0000E+31 6 0 0 -2147483647 2015 64.576551 13 50 14 0 59.0493 7.0615E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 64.580023 13 55 14 0 59.0541 7.0610E-03 2.1183E-03 0.0000E+00 -1.0000E+31 3 1 0 -2147483647 2015 64.621690 14 55 14 0 59.0584 9.4140E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 64.628634 15 5 14 0 59.0571 1.4121E-02 2.1182E-03 1.0591E-03 -1.0000E+31 6 1 1 -2147483647 2015 64.639051 15 20 14 0 59.0595 1.6474E-02 0.0000E+00 0.0000E+00 -1.0000E+31 7 0 0 -2147483647
