/* ** ** Swift/XRT hardness ratio for 3C 279. ** 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 54949.883267 0.000973 0.54824 0.15374 0.98507 1 0.27437 0.04600 0.22031 0.03693 0.15042 0.03381 0.12060 0.02711 54949.884851 0.000610 0.83188 0.25435 1.00000 1 0.28566 0.05957 0.23000 0.04796 0.23763 0.05314 0.19048 0.04259 54949.885998 0.000508 0.95284 0.29771 1.00000 1 0.29702 0.06482 0.24000 0.05237 0.28301 0.06328 0.22857 0.05111 54949.887770 0.001264 0.38343 0.10133 0.97701 1 0.30224 0.04200 0.24424 0.03394 0.11589 0.02605 0.09365 0.02105 54949.890094 0.001060 0.45189 0.12240 1.00000 1 0.30009 0.04588 0.24169 0.03695 0.13561 0.03032 0.10959 0.02451 54949.892796 0.001641 0.40572 0.08861 0.99602 1 0.32502 0.03863 0.26126 0.03105 0.13187 0.02416 0.10626 0.01947 54949.953767 0.000813 0.53210 0.14469 0.96429 1 0.35933 0.05829 0.29231 0.04742 0.19120 0.04172 0.15556 0.03395 54949.956106 0.001525 0.28570 0.07079 0.98095 1 0.34974 0.04105 0.28548 0.03351 0.09992 0.02180 0.08155 0.01780 54949.958430 0.000799 0.51248 0.14238 1.00000 1 0.34769 0.05732 0.28384 0.04680 0.17819 0.03984 0.14546 0.03252 54949.960434 0.001206 0.48903 0.13405 0.98795 1 0.24439 0.03874 0.19950 0.03163 0.11951 0.02672 0.09756 0.02182 54949.963441 0.001801 0.54039 0.11141 0.99101 1 0.27154 0.03344 0.22165 0.02730 0.14674 0.02426 0.11978 0.01981
