/* ** ** 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 54976.119780 0.002397 0.34915 0.09052 0.96364 1 0.20740 0.02722 0.14649 0.01921 0.07242 0.01619 0.05031 0.01125 54976.186281 0.001830 0.46514 0.12658 1.00000 1 0.16973 0.02632 0.13705 0.02125 0.07895 0.01766 0.06349 0.01420 54976.190929 0.002818 0.40700 0.08428 0.97761 1 0.21185 0.02375 0.17101 0.01917 0.08622 0.01501 0.06960 0.01212 54976.253301 0.001830 0.41420 0.11066 0.96032 1 0.19383 0.02798 0.15868 0.02290 0.08029 0.01805 0.06578 0.01479 54976.256657 0.001525 0.41503 0.11096 0.98095 1 0.22855 0.03349 0.18718 0.02743 0.09485 0.02121 0.07767 0.01737 54976.262060 0.003878 0.29158 0.05713 0.99189 1 0.21428 0.02009 0.17523 0.01643 0.06248 0.01075 0.05120 0.00881
