STEREO LET LEVEL 1 combined proton data for ahead spacecraft, for 2015-053 Verified Data - OK to distribute File created: Sun Apr 26 10:36:48 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 proton intensity (1/(cm^2 s sr MeV/nuc)) Column 9: 4.0 - 6.0 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 10: 6.0 - 10.0 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 11: 10.0 - 15.0 MeV proton intensity (1/(cm^2 s sr MeV/nuc)) Column 12 - 15: 4 proton 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 53.843924 20 15 15 0 58.8210 5.1915E+00 8.9533E-01 1.3611E-01 -1.0000E+31 2197 421 128 -2147483647 2015 53.847396 20 20 15 0 58.8303 5.0135E+00 8.0376E-01 1.3821E-01 -1.0000E+31 2122 378 130 -2147483647 2015 53.850868 20 25 15 0 58.7498 6.3594E+00 1.0944E+00 1.6928E-01 -1.0000E+31 2688 514 159 -2147483647 2015 53.854340 20 30 15 0 58.7163 6.7134E+00 1.1270E+00 1.9281E-01 -1.0000E+31 2836 529 181 -2147483647 2015 53.857813 20 35 15 0 58.7888 5.9391E+00 8.4263E-01 1.6491E-01 -1.0000E+31 2512 396 155 -2147483647 2015 53.861285 20 40 15 0 58.8111 5.2089E+00 8.3806E-01 1.5953E-01 -1.0000E+31 2204 394 150 -2147483647 2015 53.868229 20 50 15 0 58.7305 6.6337E+00 1.0863E+00 1.7359E-01 -1.0000E+31 2803 510 163 -2147483647 2015 53.871701 20 55 15 0 58.7882 5.3788E+00 7.7880E-01 1.5533E-01 -1.0000E+31 2275 366 146 -2147483647 2015 53.875174 21 0 15 0 58.7550 5.8455E+00 9.6021E-01 1.6713E-01 -1.0000E+31 2471 451 157 -2147483647 2015 53.937674 22 30 15 0 58.5198 8.8498E+00 1.3830E+00 2.2659E-01 -1.0000E+31 3726 647 212 -2147483647
