/* ** ** Swift/XRT hardness ratio for 3C 273. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56674.702504 0.000428 0.32952 0.05410 0.99324 0 2.46371 0.20198 2.06534 0.16929 0.81184 0.11548 0.67792 0.09643 56674.703300 0.000367 0.40444 0.06956 0.94488 0 2.37271 0.21724 2.01057 0.18407 0.95961 0.13973 0.81336 0.11843 56674.704038 0.000370 0.35624 0.06025 0.97656 0 2.57940 0.22189 2.19117 0.18849 0.91890 0.13380 0.78083 0.11370 56674.704831 0.000417 0.35427 0.05908 0.97917 0 2.34112 0.20065 1.98489 0.17012 0.82939 0.11866 0.70313 0.10060 56674.705603 0.000356 0.44253 0.07762 0.99187 0 2.13330 0.20862 1.80749 0.17676 0.94405 0.13746 0.80003 0.11649 56674.706330 0.000370 0.44411 0.07598 0.96875 0 2.13215 0.20264 1.80908 0.17194 0.94692 0.13469 0.80366 0.11431 56674.707128 0.000428 0.41782 0.07010 0.94595 0 2.01807 0.18218 1.71287 0.15463 0.84319 0.11925 0.71548 0.10118 56674.707898 0.000341 0.38653 0.06529 0.97458 0 2.61704 0.23145 2.21901 0.19625 1.01157 0.14558 0.85764 0.12342 56674.708783 0.000544 0.30221 0.04906 0.97340 0 2.15784 0.16794 1.81520 0.14126 0.65212 0.09290 0.54990 0.07833 56674.709701 0.000373 0.40512 0.06831 0.99225 0 2.27843 0.20925 1.93065 0.17731 0.92304 0.13054 0.78255 0.11067 56674.710470 0.000396 0.40929 0.07005 0.97810 0 2.12300 0.19663 1.79791 0.16653 0.86893 0.12505 0.73603 0.10592 56674.711191 0.000324 0.54309 0.09640 1.00000 0 1.96036 0.20976 1.66223 0.17787 1.06466 0.15079 0.90308 0.12790 56674.711839 0.000324 0.41256 0.07013 0.97321 0 2.60290 0.23891 2.20507 0.20239 1.07385 0.15364 0.90955 0.13013 56674.712632 0.000469 0.30700 0.05033 0.97531 0 2.41337 0.19323 2.04481 0.16372 0.74090 0.10600 0.62748 0.08977 56674.713506 0.000399 0.34055 0.05639 0.98551 0 2.55285 0.21191 2.16125 0.17940 0.86937 0.12455 0.73617 0.10547 56674.714304 0.000399 0.31000 0.05112 0.97826 0 2.79464 0.22482 2.35677 0.18957 0.86635 0.12471 0.73058 0.10514 56674.715080 0.000376 0.38933 0.06677 0.97692 0 2.34981 0.21614 1.98589 0.18267 0.91486 0.13242 0.77257 0.11183 56674.716052 0.000596 0.42731 0.05143 0.98058 0 2.72689 0.18026 2.30928 0.15266 1.16523 0.11720 0.98667 0.09924
