STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-011 Verified Data - OK to distribute File created: Tue Apr 7 10:35:56 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 11.354410 8 30 21 0 59.1267 3.2911E-02 0.0000E+00 1.0578E-03 -1.0000E+31 14 0 1 -2147483647 2015 11.357882 8 35 21 0 59.1244 3.0561E-02 4.2315E-03 0.0000E+00 -1.0000E+31 13 2 0 -2147483647 2015 11.361354 8 40 21 0 59.1244 3.7614E-02 4.2315E-03 0.0000E+00 -1.0000E+31 16 2 0 -2147483647 2015 11.364826 8 45 21 0 59.1242 3.5263E-02 2.1158E-03 1.0579E-03 -1.0000E+31 15 1 1 -2147483647 2015 11.368299 8 50 21 0 59.1277 2.5858E-02 2.1157E-03 1.0578E-03 -1.0000E+31 11 1 1 -2147483647 2015 11.371771 8 55 21 0 59.1304 2.8207E-02 2.1156E-03 0.0000E+00 -1.0000E+31 12 1 0 -2147483647 2015 11.375243 9 0 21 0 59.1270 2.8209E-02 4.2314E-03 0.0000E+00 -1.0000E+31 12 2 0 -2147483647 2015 11.382188 9 10 21 0 59.1172 3.9969E-02 1.0580E-02 0.0000E+00 -1.0000E+31 17 5 0 -2147483647 2015 11.385660 9 15 21 0 59.1187 3.9968E-02 4.2320E-03 3.1740E-03 -1.0000E+31 17 2 3 -2147483647 2015 11.389132 9 20 21 0 59.1234 4.2316E-02 8.4632E-03 1.0579E-03 -1.0000E+31 18 4 1 -2147483647 2015 11.392604 9 25 21 0 59.1221 3.7615E-02 2.1159E-03 2.1159E-03 -1.0000E+31 16 1 2 -2147483647 2015 11.396076 9 30 21 0 59.1231 3.5264E-02 8.4633E-03 4.2316E-03 -1.0000E+31 15 4 4 -2147483647 2015 11.399549 9 35 21 0 59.1243 2.8210E-02 2.1158E-03 0.0000E+00 -1.0000E+31 12 1 0 -2147483647 2015 11.403021 9 40 21 0 59.1254 2.3508E-02 4.2315E-03 1.0579E-03 -1.0000E+31 10 2 1 -2147483647 2015 11.406493 9 45 21 0 59.1269 2.8209E-02 1.0578E-02 0.0000E+00 -1.0000E+31 12 5 0 -2147483647 2015 11.409965 9 50 21 0 59.1279 1.8806E-02 6.3469E-03 0.0000E+00 -1.0000E+31 8 3 0 -2147483647 2015 11.413438 9 55 21 0 59.1266 2.1157E-02 2.1157E-03 0.0000E+00 -1.0000E+31 9 1 0 -2147483647 2015 11.416910 10 0 21 0 59.1264 3.0560E-02 2.1157E-03 0.0000E+00 -1.0000E+31 13 1 0 -2147483647 2015 11.420382 10 5 21 0 59.1278 2.3507E-02 4.2313E-03 0.0000E+00 -1.0000E+31 10 2 0 -2147483647 2015 11.423854 10 10 21 0 59.1305 3.7610E-02 2.1156E-03 3.1733E-03 -1.0000E+31 16 1 3 -2147483647 2015 11.427326 10 15 21 0 59.1267 2.8209E-02 0.0000E+00 0.0000E+00 -1.0000E+31 12 0 0 -2147483647 2015 11.430799 10 20 21 0 59.1291 2.1156E-02 4.2312E-03 2.1156E-03 -1.0000E+31 9 2 2 -2147483647 2015 11.434271 10 25 21 0 59.1254 3.5262E-02 6.3472E-03 0.0000E+00 -1.0000E+31 15 3 0 -2147483647 2015 11.437743 10 30 21 0 59.1278 9.4029E-03 4.2313E-03 0.0000E+00 -1.0000E+31 4 2 0 -2147483647 2015 11.441215 10 35 21 0 59.1305 2.5857E-02 6.3467E-03 1.0578E-03 -1.0000E+31 11 3 1 -2147483647 2015 11.444688 10 40 21 0 59.1240 4.4667E-02 2.1158E-03 0.0000E+00 -1.0000E+31 19 1 0 -2147483647 2015 11.448160 10 45 21 0 59.1255 1.6456E-02 2.1157E-03 2.1157E-03 -1.0000E+31 7 1 2 -2147483647 2015 11.451632 10 50 21 0 59.1292 3.2909E-02 6.3468E-03 2.1156E-03 -1.0000E+31 14 3 2 -2147483647 2015 11.455104 10 55 21 0 59.1266 2.5858E-02 4.2314E-03 0.0000E+00 -1.0000E+31 11 2 0 -2147483647 2015 11.458576 11 0 21 0 59.1240 2.3509E-02 4.2316E-03 0.0000E+00 -1.0000E+31 10 2 0 -2147483647 2015 11.462049 11 5 21 0 59.1266 2.1157E-02 0.0000E+00 2.1157E-03 -1.0000E+31 9 0 2 -2147483647 2015 11.465521 11 10 21 0 59.1277 1.4104E-02 2.1157E-03 2.1157E-03 -1.0000E+31 6 1 2 -2147483647 2015 11.468993 11 15 21 0 59.1291 3.9961E-02 4.2312E-03 0.0000E+00 -1.0000E+31 17 2 0 -2147483647 2015 11.472465 11 20 21 0 59.1290 3.2909E-02 8.4624E-03 1.0578E-03 -1.0000E+31 14 4 1 -2147483647 2015 11.475938 11 25 21 0 59.1313 1.4104E-02 4.2311E-03 0.0000E+00 -1.0000E+31 6 2 0 -2147483647 2015 11.479410 11 30 21 0 59.1311 1.6454E-02 0.0000E+00 2.1155E-03 -1.0000E+31 7 0 2 -2147483647 2015 11.482882 11 35 21 0 59.1337 1.8804E-02 6.3463E-03 0.0000E+00 -1.0000E+31 8 3 0 -2147483647
