STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-066 Verified Data - OK to distribute File created: Mon May 25 10:34:41 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 66.864734 20 45 13 1 56.9662 4.2001E-01 7.0002E-02 -1.0000E+31 39 13 -2147483647 2015 66.868206 20 50 13 1 57.0248 4.5185E-01 6.4550E-02 -1.0000E+31 42 12 -2147483647 2015 66.871678 20 55 13 1 57.1493 5.1528E-01 8.0512E-02 -1.0000E+31 48 15 -2147483647 2015 66.875150 21 0 13 1 57.2314 2.8943E-01 7.5037E-02 -1.0000E+31 27 14 -2147483647 2015 66.878623 21 5 13 1 57.1325 3.2214E-01 8.5905E-02 -1.0000E+31 30 16 -2147483647 2015 66.882095 21 10 13 1 56.6509 4.7649E-01 8.1221E-02 -1.0000E+31 44 15 -2147483647 2015 66.885567 21 15 13 1 56.8190 4.7509E-01 4.8588E-02 -1.0000E+31 44 9 -2147483647 2015 66.889039 21 20 13 1 57.3198 2.6758E-01 8.0273E-02 -1.0000E+31 25 15 -2147483647 2015 66.892512 21 25 13 1 57.1342 3.2213E-01 3.2213E-02 -1.0000E+31 30 6 -2147483647 2015 66.944595 22 40 13 1 57.2620 2.3571E-01 5.3569E-02 -1.0000E+31 22 10 -2147483647 2015 66.948067 22 45 13 1 57.3572 4.2784E-01 4.2784E-02 -1.0000E+31 40 8 -2147483647 2015 66.951539 22 50 13 1 57.4303 2.1365E-01 3.7389E-02 -1.0000E+31 20 7 -2147483647 2015 66.955012 22 55 13 1 57.4539 2.9899E-01 5.3390E-02 -1.0000E+31 28 10 -2147483647 2015 66.958484 23 0 13 1 57.5722 2.1312E-01 1.5984E-02 -1.0000E+31 20 3 -2147483647
