STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-022 Verified Data - OK to distribute File created: Tue Apr 7 10:36:49 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 22.830081 19 55 19 0 59.1459 4.2300E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 22.833553 20 0 19 0 59.1458 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.837025 20 5 19 0 59.1522 2.1148E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 22.840498 20 10 19 0 59.1521 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.843970 20 15 19 0 59.1458 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.847442 20 20 19 0 59.1484 2.1149E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 22.850914 20 25 19 0 59.1534 2.1147E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 22.857859 20 35 19 0 59.1484 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.861331 20 40 19 0 59.1458 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.864803 20 45 19 0 59.1484 2.1149E-03 1.0575E-03 -1.0000E+31 1 1 -2147483647 2015 22.868275 20 50 19 0 59.1496 2.1149E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 22.871748 20 55 19 0 59.1496 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.875220 21 0 19 0 59.1496 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.878692 21 5 19 0 59.1470 2.1150E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 22.882164 21 10 19 0 59.1497 0.0000E+00 1.0574E-03 -1.0000E+31 0 1 -2147483647 2015 22.885637 21 15 19 0 59.1457 2.1150E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 22.889109 21 20 19 0 59.1496 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.892581 21 25 19 0 59.1496 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.896053 21 30 19 0 59.1496 6.3446E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 22.899525 21 35 19 0 59.1495 2.1149E-03 1.0574E-03 -1.0000E+31 1 1 -2147483647 2015 22.902998 21 40 19 0 59.1457 0.0000E+00 2.1150E-03 -1.0000E+31 0 2 -2147483647 2015 22.906470 21 45 19 0 59.1457 4.2300E-03 1.0575E-03 -1.0000E+31 2 1 -2147483647 2015 22.909942 21 50 19 0 59.1508 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.913414 21 55 19 0 59.1522 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 22.916887 22 0 19 0 59.1495 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647
