STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-206 Verified Data - OK to distribute File created: Tue Sep 15 10:55:24 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 206.683021 16 23 33 0 59.1567 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.686493 16 28 33 0 59.1567 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.689965 16 33 33 0 59.1554 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.693437 16 38 33 0 59.1528 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.696910 16 43 33 0 59.1553 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.700382 16 48 33 0 59.1529 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.703854 16 53 33 0 59.1567 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.707326 16 58 33 0 59.1565 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.710799 17 3 33 0 59.1554 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.721215 17 18 33 0 59.1541 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.724687 17 23 33 0 59.1528 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.728160 17 28 33 0 59.1527 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.731632 17 33 33 0 59.1527 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.735104 17 38 33 0 59.1541 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.738576 17 43 33 0 59.1541 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.766354 18 23 33 0 59.1591 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.769826 18 28 33 0 59.1554 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 206.776771 18 38 33 0 59.1515 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647
