/* ** ** 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 56027.537628 0.000512 8.69084 1.97806 0.96610 0 0.32736 0.07076 0.26719 0.05774 2.84501 0.20269 2.32784 0.16582 56027.538702 0.000561 10.23284 2.49332 0.95361 0 0.25616 0.05969 0.21091 0.04915 2.62127 0.18683 2.15688 0.15371 56027.539810 0.000547 7.69714 1.70225 0.98942 0 0.33217 0.06950 0.27508 0.05756 2.55673 0.18322 2.11753 0.15174 56027.540889 0.000532 13.57394 3.75855 0.96196 0 0.19891 0.05316 0.16402 0.04384 2.69995 0.19536 2.23036 0.16137 56027.541942 0.000521 9.54300 2.30237 0.94444 0 0.29571 0.06812 0.24390 0.05618 2.82196 0.20221 2.32928 0.16691 56027.543082 0.000619 9.41103 2.21298 0.97635 0 0.25898 0.05812 0.21258 0.04772 2.43725 0.17105 2.00449 0.14068
