STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-201 Verified Data - OK to distribute File created: Tue Sep 15 10:54:57 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 201.575394 13 48 34 0 59.1531 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.578866 13 53 34 0 59.1530 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.582338 13 58 34 0 59.1479 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.585810 14 3 34 0 59.1505 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.589282 14 8 34 0 59.1492 2.3499E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 201.592755 14 13 34 0 59.1531 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.603171 14 28 34 0 59.1480 2.3499E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 201.606644 14 33 34 0 59.1544 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.610116 14 38 34 0 59.1506 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.613588 14 43 34 0 59.1518 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.617060 14 48 34 0 59.1519 4.6995E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 201.620532 14 53 34 0 59.1531 2.3497E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 201.637894 15 18 34 0 59.1518 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.683032 16 23 34 0 59.1508 7.0494E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 201.686505 16 28 34 0 59.1508 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.790671 18 58 34 0 59.1533 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 201.821921 19 43 34 0 59.1520 2.3498E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647
