/* ** ** 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 54117.216107 0.000613 0.52498 0.14650 0.85849 0 0.55099 0.08994 0.41583 0.06788 0.28926 0.06547 0.21770 0.04926 54117.217989 0.000988 0.56903 0.15795 0.92647 1 0.47924 0.07879 0.22425 0.03687 0.27270 0.06099 0.12699 0.02839 54117.219950 0.000973 0.54091 0.15183 1.00000 1 0.47083 0.07988 0.22146 0.03757 0.25467 0.05695 0.11940 0.02670 54117.221800 0.000876 0.92591 0.29116 0.95027 1 0.27154 0.05842 0.16047 0.03346 0.25142 0.05766 0.13954 0.03120 54117.223257 0.000581 0.78005 0.23401 1.00000 1 0.31861 0.06372 0.25641 0.05128 0.24853 0.05557 0.20000 0.04472 54117.224724 0.000886 0.44741 0.12049 0.96721 1 0.37662 0.05653 0.30309 0.04549 0.16850 0.03768 0.13559 0.03032 54117.226438 0.000828 0.44116 0.11627 0.98246 1 0.42255 0.06244 0.34002 0.05025 0.18641 0.04068 0.15000 0.03273 54117.228198 0.000932 0.47857 0.13623 0.98441 1 0.44143 0.07219 0.26605 0.04207 0.21126 0.04922 0.12594 0.02834 54117.230204 0.001075 0.43569 0.11743 0.95946 1 0.54331 0.08058 0.25780 0.03822 0.23672 0.05328 0.11200 0.02520 54117.232644 0.001365 0.43159 0.10375 0.99098 1 0.53779 0.07171 0.24896 0.03320 0.23210 0.04642 0.10735 0.02147
