/* ** ** 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 54828.207020 0.001699 0.32716 0.08452 1.00000 1 0.26706 0.03454 0.20835 0.02694 0.08737 0.01954 0.06838 0.01529 54828.209867 0.001148 0.59114 0.16774 0.98734 1 0.22094 0.03859 0.17316 0.03024 0.13061 0.02921 0.10256 0.02293 54828.214457 0.003443 0.38911 0.07351 0.93058 1 0.23187 0.02324 0.18192 0.01823 0.09022 0.01445 0.07073 0.01133 54828.280778 0.003922 0.44055 0.08509 0.96189 1 0.36681 0.03913 0.13450 0.01434 0.16160 0.02602 0.05991 0.00962 54828.347226 0.000784 0.67161 0.19612 0.96296 1 0.27841 0.05189 0.22667 0.04224 0.18698 0.04203 0.15308 0.03441 54828.349695 0.001685 0.63916 0.15536 0.98407 1 0.18751 0.02866 0.15321 0.02342 0.11985 0.02265 0.09811 0.01854
