STEREO LET LEVEL 1 combined 4He data for ahead spacecraft, for 2015-048 Verified Data - OK to distribute File created: Sun Apr 26 10:36:31 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 48.784907 18 50 16 0 59.1486 4.6998E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 48.788380 18 55 16 0 59.1472 9.3998E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 48.791852 19 0 16 0 59.1460 7.0500E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 48.795324 19 5 16 0 59.1448 4.7001E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 48.798796 19 10 16 0 59.1460 9.4000E-03 2.1150E-03 0.0000E+00 -1.0000E+31 4 1 0 -2147483647 2015 48.802269 19 15 16 0 59.1497 9.3994E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 48.805741 19 20 16 0 59.1497 4.6997E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 48.809213 19 25 16 0 59.1472 7.0499E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 48.812685 19 30 16 0 59.1459 0.0000E+00 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 0 -2147483647 2015 48.816157 19 35 16 0 59.1485 2.3499E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 48.819630 19 40 16 0 59.1486 2.3499E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 48.823102 19 45 16 0 59.1461 4.7000E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 48.878657 21 5 16 0 59.1498 4.6997E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647
