STEREO LET LEVEL 1 combined proton data for ahead spacecraft, for 2015-217 Verified Data - OK to distribute File created: Wed Nov 4 10:57:26 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: 1.8 - 3.6 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 4.0 - 6.0 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 6.0 - 10.0 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 11: 10.0 - 15.0 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 12 - 15: 4 proton 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 217.585787 14 3 32 0 59.1540 7.0490E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 217.589259 14 8 32 0 59.1553 4.6993E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 217.592731 14 13 32 0 59.1541 7.0490E-03 2.1147E-03 0.0000E+00 -1.0000E+31 3 1 0 -2147483647 2015 217.596204 14 18 32 0 59.1554 4.6993E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 217.599676 14 23 32 0 59.1566 2.3496E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 217.603148 14 28 32 0 59.1502 4.6997E-03 0.0000E+00 0.0000E+00 -1.0000E+31 2 0 0 -2147483647 2015 217.613565 14 43 32 0 59.1515 7.0493E-03 0.0000E+00 0.0000E+00 -1.0000E+31 3 0 0 -2147483647 2015 217.617037 14 48 32 0 59.1502 7.0495E-03 2.1148E-03 0.0000E+00 -1.0000E+31 3 1 0 -2147483647 2015 217.620509 14 53 32 0 59.1567 2.3496E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647
