/* ** ** 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 55975.936106 0.000654 9.00469 2.09941 0.96460 0 0.24092 0.05346 0.20255 0.04494 2.16945 0.15521 1.81910 0.13013 55975.937495 0.000735 11.12616 2.90422 0.97244 0 0.17212 0.04321 0.14424 0.03621 1.91501 0.13699 1.60552 0.11485 55975.938831 0.000602 8.54010 1.96628 0.98077 0 0.27330 0.05983 0.22776 0.04986 2.33402 0.16648 1.94897 0.13902 55975.940081 0.000648 9.52234 2.29495 0.96875 0 0.23483 0.05406 0.19327 0.04450 2.23615 0.15937 1.84358 0.13140 55975.941412 0.000683 10.17161 2.48647 0.94915 0 0.20706 0.04839 0.17355 0.04055 2.10616 0.15111 1.76579 0.12669 55975.942772 0.000677 7.22744 1.52633 0.98291 0 0.28212 0.05595 0.23550 0.04670 2.03902 0.14803 1.70189 0.12354 55975.944236 0.000787 6.39103 1.27402 0.96691 0 0.28443 0.05294 0.23725 0.04416 1.81780 0.12971 1.51546 0.10813 55975.945666 0.000642 10.25507 2.56429 0.97748 0 0.21480 0.05147 0.17863 0.04279 2.20277 0.15759 1.82748 0.13073 55975.947003 0.000694 6.70578 1.38302 0.95833 0 0.31359 0.06062 0.25591 0.04948 2.10284 0.15110 1.71750 0.12340 55975.948834 0.001137 11.56228 2.32368 0.97201 0 0.18580 0.03593 0.15439 0.02985 2.14833 0.11751 1.78122 0.09743
