STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-226 Verified Data - OK to distribute File created: Wed Nov 4 10:58:06 PST 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 226.005914 0 8 31 0 59.1566 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.009387 0 13 31 0 59.1528 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.012859 0 18 31 0 59.1514 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.585775 14 3 31 0 59.1527 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.589248 14 8 31 0 59.1578 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.592720 14 13 31 0 59.1553 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.596192 14 18 31 0 59.1554 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.599664 14 23 31 0 59.1553 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.603137 14 28 31 0 59.1527 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.606609 14 33 31 0 59.1579 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.617025 14 48 31 0 59.1553 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.620498 14 53 31 0 59.1528 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.623970 14 58 31 0 59.1553 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.728137 17 28 31 0 59.1566 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.735081 17 38 31 0 59.1527 0.0000E+00 1.0574E-03 -1.0000E+31 0 1 -2147483647 2015 226.811470 19 28 31 0 59.1566 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 226.818414 19 38 31 0 59.1540 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647
