STEREO LET LEVEL 1 combined proton data for ahead spacecraft, for 2015-020 Verified Data - OK to distribute File created: Tue Apr 7 10:36:38 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 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 20.135637 3 15 19 0 59.1439 1.2455E-01 5.2877E-02 2.2208E-02 -1.0000E+31 53 25 21 -2147483647 2015 20.139109 3 20 19 0 59.1437 8.6953E-02 4.6532E-02 2.4323E-02 -1.0000E+31 37 22 23 -2147483647 2015 20.142581 3 25 19 0 59.1438 1.0810E-01 6.7683E-02 2.5381E-02 -1.0000E+31 46 32 24 -2147483647 2015 20.146053 3 30 19 0 59.1400 1.0811E-01 6.3457E-02 2.8555E-02 -1.0000E+31 46 30 27 -2147483647 2015 20.149525 3 35 19 0 59.1464 1.3395E-01 6.3450E-02 2.7495E-02 -1.0000E+31 57 30 26 -2147483647 2015 20.152998 3 40 19 0 59.1450 1.3160E-01 5.4991E-02 2.0093E-02 -1.0000E+31 56 26 19 -2147483647 2015 20.156470 3 45 19 0 59.1450 1.1515E-01 5.2876E-02 7.4026E-03 -1.0000E+31 49 25 7 -2147483647 2015 20.163414 3 55 19 0 59.1412 1.4101E-01 5.4995E-02 2.0094E-02 -1.0000E+31 60 26 19 -2147483647 2015 20.166887 4 0 19 0 59.1475 1.1750E-01 5.4989E-02 1.7977E-02 -1.0000E+31 50 26 17 -2147483647 2015 20.170359 4 5 19 0 59.1449 1.1280E-01 5.9221E-02 2.1150E-02 -1.0000E+31 48 28 20 -2147483647 2015 20.173831 4 10 19 0 59.1438 1.0810E-01 5.7107E-02 2.8554E-02 -1.0000E+31 46 27 27 -2147483647 2015 20.177303 4 15 19 0 59.1450 1.2690E-01 6.3451E-02 1.6920E-02 -1.0000E+31 54 30 16 -2147483647 2015 20.180775 4 20 19 0 59.1462 1.0575E-01 6.3450E-02 1.5862E-02 -1.0000E+31 45 30 15 -2147483647 2015 20.184248 4 25 19 0 59.1438 1.2925E-01 6.3452E-02 1.3748E-02 -1.0000E+31 55 30 13 -2147483647 2015 20.187720 4 30 19 0 59.1451 1.0105E-01 5.0761E-02 2.4323E-02 -1.0000E+31 43 24 23 -2147483647 2015 20.191192 4 35 19 0 59.1449 9.8702E-02 6.3451E-02 1.6920E-02 -1.0000E+31 42 30 16 -2147483647 2015 20.194664 4 40 19 0 59.1437 1.1515E-01 4.0187E-02 1.5863E-02 -1.0000E+31 49 19 15 -2147483647 2015 20.198137 4 45 19 0 59.1450 7.7551E-02 5.2876E-02 1.2690E-02 -1.0000E+31 33 25 12 -2147483647 2015 20.201609 4 50 19 0 59.1450 1.3865E-01 4.6531E-02 1.9035E-02 -1.0000E+31 59 22 18 -2147483647 2015 20.205081 4 55 19 0 59.1488 9.8695E-02 4.8643E-02 2.1149E-02 -1.0000E+31 42 23 20 -2147483647 2015 20.208553 5 0 19 0 59.1425 9.1655E-02 4.4418E-02 2.3266E-02 -1.0000E+31 39 21 22 -2147483647 2015 20.212025 5 5 19 0 59.1437 8.9304E-02 4.4417E-02 2.1151E-02 -1.0000E+31 38 21 20 -2147483647
