/* ** ** 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 55224.842547 0.000567 13.62242 3.92820 0.98469 0 0.20254 0.05659 0.14714 0.04081 2.75906 0.19662 2.08594 0.14763 55224.843652 0.000538 9.07555 2.08740 0.95161 0 0.30868 0.06737 0.24318 0.05307 2.80147 0.20346 2.21061 0.16055 55224.844795 0.000599 9.21289 2.14220 0.94686 0 0.27799 0.06152 0.21983 0.04865 2.56113 0.18272 2.02825 0.14469 55224.845883 0.000489 7.95527 1.75350 0.95858 0 0.38935 0.08119 0.30924 0.06448 3.09737 0.22131 2.45071 0.17509 55224.847156 0.000784 8.69931 1.69089 0.97064 0 0.31374 0.05799 0.24705 0.04567 2.72930 0.16411 2.14643 0.12904 55224.909381 0.000735 8.80106 2.08063 0.95276 0 0.32612 0.07319 0.19272 0.04177 2.87018 0.21319 1.64491 0.11717 55224.910706 0.000590 9.59403 2.37958 0.95098 0 0.36463 0.08662 0.21462 0.05096 3.49824 0.24934 2.05687 0.14657 55224.911896 0.000599 11.21673 2.88299 0.96135 0 0.29413 0.07262 0.17934 0.04426 3.29921 0.23580 1.99512 0.14254 55224.913551 0.001056 12.61639 2.87210 0.97547 0 0.23364 0.05145 0.13586 0.02995 2.94774 0.17013 1.71674 0.09907
