STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-037 Verified Data - OK to distribute File created: Sun Apr 26 10:35:40 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 37.239780 5 45 17 0 59.1491 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.243252 5 50 17 0 59.1530 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.246725 5 55 17 0 59.1504 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.250197 6 0 17 0 59.1517 2.1148E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 37.253669 6 5 17 0 59.1491 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.257141 6 10 17 0 59.1479 2.1149E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 37.260613 6 15 17 0 59.1555 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.264086 6 20 17 0 59.1543 2.1147E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 37.267558 6 25 17 0 59.1530 0.0000E+00 1.0574E-03 -1.0000E+31 0 1 -2147483647 2015 37.271030 6 30 17 0 59.1528 0.0000E+00 1.0574E-03 -1.0000E+31 0 1 -2147483647 2015 37.854363 20 30 17 0 59.1555 0.0000E+00 2.1147E-03 -1.0000E+31 0 2 -2147483647 2015 37.857836 20 35 17 0 59.1531 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.861308 20 40 17 0 59.1530 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.864780 20 45 17 0 59.1505 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.868252 20 50 17 0 59.1517 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.871725 20 55 17 0 59.1555 2.1147E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 37.875197 21 0 17 0 59.1529 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.878669 21 5 17 0 59.1531 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.882141 21 10 17 0 59.1531 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.885613 21 15 17 0 59.1492 4.2298E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 37.889086 21 20 17 0 59.1530 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 37.896030 21 30 17 0 59.1492 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647
