STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-065 Verified Data - OK to distribute File created: Mon May 25 10:34:36 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 65.805706 19 20 13 0 56.0198 1.3299E+00 6.2301E-01 2.1437E-01 -1.0000E+31 536 279 192 -2147483647 2015 65.809178 19 25 13 0 53.5358 2.0744E+00 9.3699E-01 3.2596E-01 -1.0000E+31 799 401 279 -2147483647 2015 65.812650 19 30 13 0 52.8827 2.4102E+00 9.3201E-01 2.9332E-01 -1.0000E+31 917 394 248 -2147483647 2015 65.816123 19 35 13 0 53.2893 3.0047E+00 1.3756E+00 3.9789E-01 -1.0000E+31 1152 586 339 -2147483647 2015 65.819595 19 40 13 0 56.6368 6.1598E-01 3.6885E-01 9.3870E-02 -1.0000E+31 251 167 85 -2147483647 2015 65.823067 19 45 13 1 56.6420 3.3938E+00 1.9063E+00 5.4697E-01 -1.0000E+31 282 176 101 -2147483647 2015 65.826539 19 50 13 1 56.6847 3.1627E+00 1.4827E+00 5.2491E-01 -1.0000E+31 263 137 97 -2147483647 2015 65.830012 19 55 13 1 56.2766 3.6823E+00 1.6570E+00 5.9958E-01 -1.0000E+31 304 152 110 -2147483647 2015 65.836956 20 5 13 1 55.8696 4.4046E+00 2.0864E+00 4.8316E-01 -1.0000E+31 361 190 88 -2147483647 2015 65.840428 20 10 13 1 55.6832 4.2479E+00 1.9501E+00 5.0681E-01 -1.0000E+31 347 177 92 -2147483647 2015 65.843900 20 15 13 1 56.0970 3.4632E+00 1.8264E+00 5.7963E-01 -1.0000E+31 285 167 106 -2147483647 2015 65.885567 21 15 13 1 55.0238 7.9163E+00 2.5867E+00 7.4703E-01 -1.0000E+31 639 232 134 -2147483647 2015 65.889039 21 20 13 1 55.3694 6.5372E+00 2.4265E+00 6.8142E-01 -1.0000E+31 531 219 123 -2147483647 2015 65.892512 21 25 13 1 55.2778 7.5469E+00 2.7968E+00 6.9920E-01 -1.0000E+31 612 252 126 -2147483647 2015 65.899456 21 35 13 1 55.2163 9.0738E+00 2.5221E+00 7.7776E-01 -1.0000E+31 735 227 140 -2147483647 2015 65.902928 21 40 13 1 54.7772 8.3003E+00 2.8784E+00 7.9519E-01 -1.0000E+31 667 257 142 -2147483647 2015 65.968900 23 15 13 1 56.5502 5.0025E+00 2.1589E+00 5.6413E-01 -1.0000E+31 415 199 104 -2147483647 2015 65.972373 23 20 13 1 55.9680 6.5526E+00 2.3567E+00 6.7962E-01 -1.0000E+31 538 215 124 -2147483647 2015 65.975845 23 25 13 1 54.9421 8.2630E+00 2.3449E+00 5.5831E-01 -1.0000E+31 666 210 100 -2147483647 2015 65.979317 23 30 13 1 55.3913 6.0547E+00 2.0158E+00 5.6486E-01 -1.0000E+31 492 182 102 -2147483647 2015 65.982789 23 35 13 1 56.2294 3.9642E+00 1.6475E+00 4.5825E-01 -1.0000E+31 327 151 84 -2147483647 2015 65.986262 23 40 13 1 56.1978 4.4880E+00 1.4410E+00 4.4213E-01 -1.0000E+31 370 132 81 -2147483647
