STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-078 Verified Data - OK to distribute File created: Mon May 25 10:35:26 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: 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 78.343889 8 15 12 0 59.0938 7.0562E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 78.347361 8 20 12 0 59.0961 4.7040E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 78.350833 8 25 12 0 59.0935 2.3521E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 78.357778 8 35 12 0 59.0923 9.4085E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 78.361250 8 40 12 0 59.0913 1.1761E-02 0.0000E+00 0.0000E+00 -1.0000E+31 5 0 0 -2147483647 2015 78.364722 8 45 12 0 59.0915 7.0565E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 78.375139 9 0 12 0 59.0962 2.1168E-02 0.0000E+00 0.0000E+00 -1.0000E+31 9 0 0 -2147483647 2015 78.378611 9 5 12 0 59.0904 4.7044E-03 2.1170E-03 0.0000E+00 -1.0000E+31 2 1 0 -2147483647 2015 78.389028 9 20 12 0 59.0877 7.0570E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 78.392500 9 25 12 0 59.0928 4.7042E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 78.948056 22 45 12 0 59.1446 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 78.951528 22 50 12 0 59.1486 2.3499E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 78.958472 23 0 12 0 59.1511 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 78.961944 23 5 12 0 59.1472 2.3500E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 78.965417 23 10 12 0 59.1447 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 78.975833 23 25 12 0 59.1472 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 78.979306 23 30 12 0 59.1459 0.0000E+00 0.0000E+00 2.1150E-03 -1.0000E+31 0 0 2 -2147483647 2015 78.986250 23 40 12 0 59.1459 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 78.989722 23 45 12 0 59.1486 4.6998E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647
