STEREO LET LEVEL 1 combined Helium data for ahead spacecraft, for 2015-021 Verified Data - OK to distribute File created: Tue Apr 7 10:36:43 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 21.156470 3 45 19 0 59.1360 4.2307E-03 1.0577E-03 -1.0000E+31 2 1 -2147483647 2015 21.159942 3 50 19 0 59.1322 6.3465E-03 2.1155E-03 -1.0000E+31 3 2 -2147483647 2015 21.163414 3 55 19 0 59.1309 6.3466E-03 1.0578E-03 -1.0000E+31 3 1 -2147483647 2015 21.166887 4 0 19 0 59.1347 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 21.173831 4 10 19 0 59.1333 2.1155E-03 1.0577E-03 -1.0000E+31 1 1 -2147483647 2015 21.177303 4 15 19 0 59.1346 0.0000E+00 1.0577E-03 -1.0000E+31 0 1 -2147483647 2015 21.180775 4 20 19 0 59.1346 1.4808E-02 0.0000E+00 -1.0000E+31 7 0 -2147483647 2015 21.184248 4 25 19 0 59.1370 4.2306E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 21.191192 4 35 19 0 59.1321 2.1155E-03 3.1732E-03 -1.0000E+31 1 3 -2147483647 2015 21.194664 4 40 19 0 59.1322 0.0000E+00 1.0577E-03 -1.0000E+31 0 1 -2147483647 2015 21.198137 4 45 19 0 59.1347 6.3462E-03 1.0577E-03 -1.0000E+31 3 1 -2147483647 2015 21.201609 4 50 19 0 59.1320 4.2310E-03 2.1155E-03 -1.0000E+31 2 2 -2147483647 2015 21.205081 4 55 19 0 59.1348 1.0577E-02 1.0577E-03 -1.0000E+31 5 1 -2147483647 2015 21.208553 5 0 19 0 59.1333 2.1155E-03 3.1732E-03 -1.0000E+31 1 3 -2147483647 2015 21.212025 5 5 19 0 59.1371 2.1153E-03 2.1153E-03 -1.0000E+31 1 2 -2147483647 2015 21.215498 5 10 19 0 59.1355 2.1154E-03 1.0577E-03 -1.0000E+31 1 1 -2147483647 2015 21.218970 5 15 19 0 59.1420 6.3454E-03 1.0576E-03 -1.0000E+31 3 1 -2147483647 2015 21.222442 5 20 19 0 59.1369 0.0000E+00 1.0577E-03 -1.0000E+31 0 1 -2147483647 2015 21.225914 5 25 19 0 59.1343 4.2308E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 21.229387 5 30 19 0 59.1382 2.1153E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 21.232859 5 35 19 0 59.1418 0.0000E+00 1.0576E-03 -1.0000E+31 0 1 -2147483647 2015 21.236331 5 40 19 0 59.1368 8.4613E-03 0.0000E+00 -1.0000E+31 4 0 -2147483647 2015 21.239803 5 45 19 0 59.1369 4.2307E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 21.243275 5 50 19 0 59.1381 6.3458E-03 1.0576E-03 -1.0000E+31 3 1 -2147483647 2015 21.812720 19 30 19 0 59.1342 4.2308E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 21.816192 19 35 19 0 59.1394 2.1152E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 21.819664 19 40 19 0 59.1406 4.2304E-03 1.0576E-03 -1.0000E+31 2 1 -2147483647 2015 21.823137 19 45 19 0 59.1382 2.1153E-03 1.0576E-03 -1.0000E+31 1 1 -2147483647 2015 21.826609 19 50 19 0 59.1382 6.3458E-03 2.1153E-03 -1.0000E+31 3 2 -2147483647 2015 21.830081 19 55 19 0 59.1341 2.1154E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 21.833553 20 0 19 0 59.1408 0.0000E+00 1.0576E-03 -1.0000E+31 0 1 -2147483647 2015 21.837025 20 5 19 0 59.1395 6.3457E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 21.840498 20 10 19 0 59.1404 4.2304E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 21.843970 20 15 19 0 59.1355 4.2308E-03 1.0577E-03 -1.0000E+31 2 1 -2147483647 2015 21.850914 20 25 19 0 59.1418 0.0000E+00 1.0576E-03 -1.0000E+31 0 1 -2147483647 2015 21.854387 20 30 19 0 59.1417 0.0000E+00 3.1727E-03 -1.0000E+31 0 3 -2147483647 2015 21.857859 20 35 19 0 59.1354 6.3461E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 21.861331 20 40 19 0 59.1403 6.3456E-03 1.0576E-03 -1.0000E+31 3 1 -2147483647 2015 21.864803 20 45 19 0 59.1454 2.1150E-03 2.1150E-03 -1.0000E+31 1 2 -2147483647 2015 21.868275 20 50 19 0 59.1404 6.3456E-03 3.1728E-03 -1.0000E+31 3 3 -2147483647 2015 21.871748 20 55 19 0 59.1391 4.2305E-03 0.0000E+00 -1.0000E+31 2 0 -2147483647 2015 21.875220 21 0 19 0 59.1429 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 21.878692 21 5 19 0 59.1441 0.0000E+00 2.1151E-03 -1.0000E+31 0 2 -2147483647 2015 21.882164 21 10 19 0 59.1429 2.1151E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 21.885637 21 15 19 0 59.1416 0.0000E+00 0.0000E+00 -1.0000E+31 0 0 -2147483647 2015 21.889109 21 20 19 0 59.1391 2.1152E-03 1.0576E-03 -1.0000E+31 1 1 -2147483647 2015 21.892581 21 25 19 0 59.1392 2.1152E-03 0.0000E+00 -1.0000E+31 1 0 -2147483647 2015 21.896053 21 30 19 0 59.1392 8.4610E-03 1.0576E-03 -1.0000E+31 4 1 -2147483647 2015 21.899525 21 35 19 0 59.1417 2.1152E-03 1.0576E-03 -1.0000E+31 1 1 -2147483647 2015 21.902998 21 40 19 0 59.1365 6.3460E-03 0.0000E+00 -1.0000E+31 3 0 -2147483647 2015 21.906470 21 45 19 0 59.1403 6.3456E-03 1.0576E-03 -1.0000E+31 3 1 -2147483647 2015 21.909942 21 50 19 0 59.1428 0.0000E+00 2.1151E-03 -1.0000E+31 0 2 -2147483647 2015 21.913414 21 55 19 0 59.1404 0.0000E+00 1.0576E-03 -1.0000E+31 0 1 -2147483647
