STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-195 Verified Data - OK to distribute File created: Tue Sep 15 10:54:26 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 195.575394 13 48 34 0 59.1541 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.578866 13 53 34 0 59.1541 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.582338 13 58 34 0 59.1541 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.585810 14 3 34 0 59.1541 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.589282 14 8 34 0 59.1566 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.603171 14 28 34 0 59.1540 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.606644 14 33 34 0 59.1566 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.610116 14 38 34 0 59.1529 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.617060 14 48 34 0 59.1528 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.624005 14 58 34 0 59.1553 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.755949 18 8 34 0 59.1527 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.769838 18 28 34 0 59.1592 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647 2015 195.853171 20 28 34 0 59.1566 -1.0000E+31 -1.0000E+31 -1.0000E+31 -2147483647 -2147483647 -2147483647
