STEREO LET LEVEL 1 combined aluminum data for behind spacecraft, for 2011-152 Verified Data - OK to distribute File created: Thu Mar 28 17:50:40 PDT 2013 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: 6.0 - 10.0 MeV/n aluminum intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 10.0 - 15.0 MeV/n aluminum intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 15.0 - 27.0 MeV/n aluminum intensity (1/(cm^2 s sr MeV/nuc)) Column 11 - 13: 3 aluminum 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
