STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-066 Verified Data - OK to distribute File created: Mon May 25 10:34:41 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 66.864734 20 45 13 1 56.9662 2.8599E+00 4.0924E-01 5.9232E-02 -1.0000E+31 239 38 11 -2147483647 2015 66.868206 20 50 13 1 57.0248 2.7494E+00 4.5185E-01 6.4550E-02 -1.0000E+31 230 42 12 -2147483647 2015 66.871678 20 55 13 1 57.1493 2.8030E+00 5.1528E-01 6.9777E-02 -1.0000E+31 235 48 13 -2147483647 2015 66.875150 21 0 13 1 57.2314 2.6442E+00 2.7871E-01 7.5037E-02 -1.0000E+31 222 26 14 -2147483647 2015 66.878623 21 5 13 1 57.1325 2.4578E+00 3.2214E-01 8.5905E-02 -1.0000E+31 206 30 16 -2147483647 2015 66.882095 21 10 13 1 56.6509 3.3331E+00 4.7649E-01 8.1221E-02 -1.0000E+31 277 44 15 -2147483647 2015 66.885567 21 15 13 1 56.8190 2.5314E+00 4.6429E-01 4.8588E-02 -1.0000E+31 211 43 9 -2147483647 2015 66.889039 21 20 13 1 57.3198 1.9266E+00 2.6758E-01 8.0273E-02 -1.0000E+31 162 25 15 -2147483647 2015 66.892512 21 25 13 1 57.1342 2.0283E+00 3.0066E-01 3.2213E-02 -1.0000E+31 170 28 6 -2147483647 2015 66.944595 22 40 13 1 57.2620 2.2975E+00 2.3571E-01 5.3569E-02 -1.0000E+31 193 22 10 -2147483647 2015 66.948067 22 45 13 1 57.3572 1.9609E+00 4.2784E-01 4.2784E-02 -1.0000E+31 165 40 8 -2147483647 2015 66.951539 22 50 13 1 57.4303 2.0890E+00 2.1365E-01 3.7389E-02 -1.0000E+31 176 20 7 -2147483647 2015 66.955012 22 55 13 1 57.4539 2.0288E+00 2.8831E-01 5.3390E-02 -1.0000E+31 171 27 10 -2147483647 2015 66.958484 23 0 13 1 57.5722 2.0247E+00 2.0247E-01 1.5984E-02 -1.0000E+31 171 19 3 -2147483647
