STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-065 Verified Data - OK to distribute File created: Mon May 25 10:34:37 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: 4.0 - 6.0 MeV/n He intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 6.0 - 10.0 MeV/n He intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 10.0 - 15.0 MeV/n He intensity (1/(cm^2 s sr MeV/nuc)) Column 11 - 13: 3 He 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 6.2748E-01 2.1884E-01 -1.0000E+31 281 196 -2147483647 2015 65.809178 19 25 13 0 53.5358 9.5569E-01 3.3063E-01 -1.0000E+31 409 283 -2147483647 2015 65.812650 19 30 13 0 52.8827 9.4620E-01 3.0160E-01 -1.0000E+31 400 255 -2147483647 2015 65.816123 19 35 13 0 53.2893 1.3991E+00 4.0846E-01 -1.0000E+31 596 348 -2147483647 2015 65.819595 19 40 13 0 56.6368 3.7548E-01 9.6079E-02 -1.0000E+31 170 87 -2147483647 2015 65.823067 19 45 13 1 56.6420 1.9171E+00 5.5780E-01 -1.0000E+31 177 103 -2147483647 2015 65.826539 19 50 13 1 56.6847 1.4936E+00 5.2491E-01 -1.0000E+31 138 97 -2147483647 2015 65.830012 19 55 13 1 56.2766 1.6897E+00 6.1593E-01 -1.0000E+31 155 113 -2147483647 2015 65.836956 20 5 13 1 55.8696 2.1193E+00 4.9963E-01 -1.0000E+31 193 91 -2147483647 2015 65.840428 20 10 13 1 55.6832 1.9722E+00 5.0681E-01 -1.0000E+31 179 92 -2147483647 2015 65.843900 20 15 13 1 56.0970 1.8482E+00 5.9056E-01 -1.0000E+31 169 108 -2147483647 2015 65.885567 21 15 13 1 55.0238 2.6425E+00 7.5818E-01 -1.0000E+31 237 136 -2147483647 2015 65.889039 21 20 13 1 55.3694 2.4598E+00 7.0358E-01 -1.0000E+31 222 127 -2147483647 2015 65.892512 21 25 13 1 55.2778 2.8523E+00 7.1030E-01 -1.0000E+31 257 128 -2147483647 2015 65.899456 21 35 13 1 55.2163 2.6110E+00 7.8331E-01 -1.0000E+31 235 141 -2147483647 2015 65.902928 21 40 13 1 54.7772 2.9232E+00 8.1759E-01 -1.0000E+31 261 146 -2147483647 2015 65.968900 23 15 13 1 56.5502 2.1589E+00 5.6413E-01 -1.0000E+31 199 104 -2147483647 2015 65.972373 23 20 13 1 55.9680 2.4115E+00 6.9606E-01 -1.0000E+31 220 127 -2147483647 2015 65.975845 23 25 13 1 54.9421 2.4119E+00 5.5831E-01 -1.0000E+31 216 100 -2147483647 2015 65.979317 23 30 13 1 55.3913 2.0601E+00 5.9809E-01 -1.0000E+31 186 108 -2147483647 2015 65.982789 23 35 13 1 56.2294 1.6802E+00 4.6370E-01 -1.0000E+31 154 85 -2147483647 2015 65.986262 23 40 13 1 56.1978 1.4847E+00 4.4213E-01 -1.0000E+31 136 81 -2147483647
