STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-222 Verified Data - OK to distribute File created: Wed Nov 4 10:57:47 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 222.061481 1 28 32 0 59.1530 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.669120 16 3 32 0 59.1540 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.672593 16 8 32 0 59.1578 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.676065 16 13 32 0 59.1540 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.679537 16 18 32 0 59.1553 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.683009 16 23 32 0 59.1552 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.686481 16 28 32 0 59.1578 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.696898 16 43 32 0 59.1527 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.700370 16 48 32 0 59.1553 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.703843 16 53 32 0 59.1578 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.707315 16 58 32 0 59.1592 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.710787 17 3 32 0 59.1528 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 222.915648 21 58 32 0 59.1541 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647
