/* ** ** Swift/XRT hardness ratio for Cen A. ** 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 56129.598384 0.000868 7.44396 1.58776 0.94667 0 0.25191 0.05062 0.18781 0.03776 1.87524 0.13421 1.39624 0.09989 56129.601023 0.001771 8.43996 1.36950 0.95854 0 0.21508 0.03313 0.15788 0.02432 1.81528 0.09266 1.33384 0.06808 56129.921529 0.000709 14.48866 4.24300 0.97551 0 0.13302 0.03775 0.11390 0.03233 1.92724 0.13898 1.64766 0.11881 56129.922949 0.000712 15.76406 4.68807 0.96748 0 0.12445 0.03593 0.10637 0.03071 1.96181 0.14005 1.67411 0.11950 56129.924376 0.000715 9.41813 2.19005 0.95142 0 0.21081 0.04666 0.17906 0.03964 1.98545 0.14145 1.69371 0.12066 56129.925849 0.000758 14.97260 4.47897 0.97328 0 0.12371 0.03596 0.10587 0.03077 1.85228 0.13117 1.58237 0.11205 56129.927530 0.000923 13.56503 3.47173 0.95298 0 0.14327 0.03552 0.12312 0.03053 1.94346 0.12327 1.67236 0.10608
