STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-069 Verified Data - OK to distribute File created: Mon May 25 10:34:54 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 69.857789 20 35 13 0 59.1005 3.2925E-02 2.1166E-03 0.0000E+00 -1.0000E+31 14 1 0 -2147483647 2015 69.861262 20 40 13 0 59.0994 1.4111E-02 0.0000E+00 0.0000E+00 -1.0000E+31 6 0 0 -2147483647 2015 69.864734 20 45 13 0 59.1004 1.1759E-02 2.1166E-03 0.0000E+00 -1.0000E+31 5 1 0 -2147483647 2015 69.868206 20 50 13 0 59.1030 1.1759E-02 4.2331E-03 0.0000E+00 -1.0000E+31 5 2 0 -2147483647 2015 69.871678 20 55 13 0 59.1031 1.8814E-02 0.0000E+00 1.0583E-03 -1.0000E+31 8 0 1 -2147483647 2015 69.875150 21 0 13 0 59.1015 2.8221E-02 2.1166E-03 0.0000E+00 -1.0000E+31 12 1 0 -2147483647 2015 69.878623 21 5 13 0 59.1013 1.8814E-02 4.2332E-03 0.0000E+00 -1.0000E+31 8 2 0 -2147483647 2015 69.882095 21 10 13 0 59.1050 1.8813E-02 6.3494E-03 0.0000E+00 -1.0000E+31 8 3 0 -2147483647 2015 69.885567 21 15 13 0 59.1052 2.5868E-02 2.1165E-03 0.0000E+00 -1.0000E+31 11 1 0 -2147483647 2015 69.892512 21 25 13 0 59.0991 1.6463E-02 4.2334E-03 0.0000E+00 -1.0000E+31 7 2 0 -2147483647 2015 69.895984 21 30 13 0 59.1008 2.1166E-02 2.1166E-03 0.0000E+00 -1.0000E+31 9 1 0 -2147483647 2015 69.899456 21 35 13 0 59.0957 7.0560E-03 4.2336E-03 2.1168E-03 -1.0000E+31 3 2 2 -2147483647 2015 69.902928 21 40 13 0 59.1052 2.1165E-02 2.1165E-03 0.0000E+00 -1.0000E+31 9 1 0 -2147483647 2015 69.906400 21 45 13 0 59.0977 2.5871E-02 0.0000E+00 1.0584E-03 -1.0000E+31 11 0 1 -2147483647 2015 69.909873 21 50 13 0 59.0994 9.4074E-03 2.1167E-03 0.0000E+00 -1.0000E+31 4 1 0 -2147483647 2015 69.913345 21 55 13 0 59.1055 1.1758E-02 2.1164E-03 1.0582E-03 -1.0000E+31 5 1 1 -2147483647 2015 69.916817 22 0 13 0 59.0921 1.4113E-02 2.1169E-03 0.0000E+00 -1.0000E+31 6 1 0 -2147483647 2015 69.920289 22 5 13 0 59.0924 2.3521E-02 4.2338E-03 0.0000E+00 -1.0000E+31 10 2 0 -2147483647 2015 69.923762 22 10 13 0 59.0912 1.4113E-02 0.0000E+00 0.0000E+00 -1.0000E+31 6 0 0 -2147483647 2015 69.927234 22 15 13 0 59.0986 2.3519E-02 0.0000E+00 0.0000E+00 -1.0000E+31 10 0 0 -2147483647 2015 69.930706 22 20 13 0 59.0938 7.0562E-03 6.3506E-03 0.0000E+00 -1.0000E+31 3 3 0 -2147483647 2015 69.934178 22 25 13 0 59.0844 1.4115E-02 2.1172E-03 1.0586E-03 -1.0000E+31 6 1 1 -2147483647 2015 69.937650 22 30 13 0 59.0951 3.0576E-02 2.1168E-03 0.0000E+00 -1.0000E+31 13 1 0 -2147483647 2015 69.941123 22 35 13 0 59.0897 1.8818E-02 0.0000E+00 1.0585E-03 -1.0000E+31 8 0 1 -2147483647 2015 69.944595 22 40 13 0 59.0959 1.1760E-02 2.1168E-03 0.0000E+00 -1.0000E+31 5 1 0 -2147483647 2015 69.948067 22 45 13 0 59.1032 2.1165E-02 2.1165E-03 0.0000E+00 -1.0000E+31 9 1 0 -2147483647 2015 69.951539 22 50 13 0 59.1041 3.5275E-02 2.1165E-03 0.0000E+00 -1.0000E+31 15 1 0 -2147483647 2015 69.955012 22 55 13 0 59.1014 2.3518E-02 0.0000E+00 0.0000E+00 -1.0000E+31 10 0 0 -2147483647 2015 69.958484 23 0 13 0 59.1039 9.4067E-03 4.2330E-03 0.0000E+00 -1.0000E+31 4 2 0 -2147483647 2015 69.961956 23 5 13 0 59.1017 2.1166E-02 2.1166E-03 0.0000E+00 -1.0000E+31 9 1 0 -2147483647 2015 69.965428 23 10 13 0 59.1001 1.4111E-02 2.1166E-03 0.0000E+00 -1.0000E+31 6 1 0 -2147483647 2015 69.968900 23 15 13 0 59.1001 1.1759E-02 6.3499E-03 0.0000E+00 -1.0000E+31 5 3 0 -2147483647 2015 69.972373 23 20 13 0 59.1086 3.2921E-02 6.3490E-03 2.1163E-03 -1.0000E+31 14 3 2 -2147483647
