STEREO LET LEVEL 1 combined 4He 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/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 20.135637 3 15 19 0 59.1439 7.0503E-03 2.1151E-03 0.0000E+00 -1.0000E+31 3 1 0 -2147483647 2015 20.139109 3 20 19 0 59.1437 4.7002E-03 4.2302E-03 1.0575E-03 -1.0000E+31 2 2 1 -2147483647 2015 20.142581 3 25 19 0 59.1438 7.0503E-03 0.0000E+00 1.0575E-03 -1.0000E+31 3 0 1 -2147483647 2015 20.146053 3 30 19 0 59.1400 1.4101E-02 6.3457E-03 0.0000E+00 -1.0000E+31 6 3 0 -2147483647 2015 20.149525 3 35 19 0 59.1464 7.0500E-03 0.0000E+00 1.0575E-03 -1.0000E+31 3 0 1 -2147483647 2015 20.152998 3 40 19 0 59.1450 2.3500E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 20.156470 3 45 19 0 59.1450 1.4100E-02 0.0000E+00 0.0000E+00 -1.0000E+31 6 0 0 -2147483647 2015 20.163414 3 55 19 0 59.1412 7.0506E-03 6.3455E-03 3.1728E-03 -1.0000E+31 3 3 3 -2147483647 2015 20.166887 4 0 19 0 59.1475 9.3998E-03 0.0000E+00 0.0000E+00 -1.0000E+31 4 0 0 -2147483647 2015 20.170359 4 5 19 0 59.1449 4.7001E-03 2.1150E-03 2.1150E-03 -1.0000E+31 2 1 2 -2147483647 2015 20.173831 4 10 19 0 59.1438 7.0503E-03 0.0000E+00 1.0575E-03 -1.0000E+31 3 0 1 -2147483647 2015 20.177303 4 15 19 0 59.1450 2.3500E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 20.180775 4 20 19 0 59.1462 2.3500E-03 4.2300E-03 0.0000E+00 -1.0000E+31 1 2 0 -2147483647 2015 20.184248 4 25 19 0 59.1438 1.1750E-02 0.0000E+00 0.0000E+00 -1.0000E+31 5 0 0 -2147483647 2015 20.187720 4 30 19 0 59.1451 1.4100E-02 0.0000E+00 2.1150E-03 -1.0000E+31 6 0 2 -2147483647 2015 20.191192 4 35 19 0 59.1449 4.7001E-03 2.1150E-03 1.0575E-03 -1.0000E+31 2 1 1 -2147483647 2015 20.194664 4 40 19 0 59.1437 1.1750E-02 2.1151E-03 0.0000E+00 -1.0000E+31 5 1 0 -2147483647 2015 20.198137 4 45 19 0 59.1450 1.6450E-02 2.1150E-03 0.0000E+00 -1.0000E+31 7 1 0 -2147483647 2015 20.201609 4 50 19 0 59.1450 2.3500E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 20.205081 4 55 19 0 59.1488 1.4099E-02 0.0000E+00 0.0000E+00 -1.0000E+31 6 0 0 -2147483647 2015 20.208553 5 0 19 0 59.1425 2.3501E-03 0.0000E+00 0.0000E+00 -1.0000E+31 1 0 0 -2147483647 2015 20.212025 5 5 19 0 59.1437 1.4101E-02 2.1151E-03 1.0575E-03 -1.0000E+31 6 1 1 -2147483647
