/* ** ** 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 55991.438898 0.000729 10.70754 2.96858 0.97222 0 0.26795 0.07154 0.13601 0.03529 2.86910 0.21447 1.59283 0.11603 55991.440400 0.000773 7.20451 1.53851 0.97004 0 0.40156 0.08065 0.20920 0.04197 2.89304 0.20985 1.51277 0.10970 55991.442041 0.000868 7.30885 1.54685 0.95667 0 0.35871 0.07140 0.18963 0.03772 2.62173 0.18858 1.38277 0.09946 55991.443777 0.000868 5.74571 1.08332 0.97000 0 0.45712 0.07981 0.24040 0.04195 2.62646 0.18698 1.37300 0.09770 55991.445542 0.000897 7.05451 1.46399 0.97419 0 0.35338 0.06876 0.18536 0.03606 2.49291 0.17983 1.30746 0.09428 55991.446772 0.000333 10.57874 4.94558 1.00000 0 0.17777 0.07951 0.09361 0.04187 1.88063 0.25591 0.97030 0.13191 55991.448537 0.001432 7.71232 1.27551 0.95960 0 0.36283 0.05665 0.18636 0.02906 2.79823 0.15261 1.44172 0.07857
