/* ** ** 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 55979.609755 0.000654 13.66176 3.80075 0.96903 0 0.19409 0.05214 0.13250 0.03559 2.65160 0.19159 1.80121 0.12963 55979.611176 0.000767 14.04919 3.96532 0.96226 0 0.15113 0.04125 0.11056 0.03018 2.12329 0.15258 1.54895 0.11131 55979.612649 0.000700 8.26724 1.86094 0.97521 0 0.27634 0.05892 0.20217 0.04310 2.28456 0.16496 1.67119 0.12067 55979.614154 0.000804 9.87889 2.45067 0.98561 0 0.19916 0.04727 0.14559 0.03455 1.96744 0.14180 1.43777 0.10362 55979.615791 0.000833 7.32382 1.56033 0.97222 0 0.26496 0.05316 0.19338 0.03879 1.94054 0.13909 1.41781 0.10162 55979.617412 0.000787 8.70734 2.00952 0.94485 0 0.23846 0.05221 0.17425 0.03816 2.07638 0.15144 1.51679 0.11062 55979.619171 0.000972 8.73029 1.78656 0.96131 0 0.24542 0.04774 0.17858 0.03474 2.14256 0.13603 1.56238 0.09920
