/* ** ** 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 55997.390745 0.000561 9.40230 2.20712 0.96907 0 0.27110 0.06063 0.22509 0.05033 2.54897 0.18192 2.11994 0.15127 55997.392191 0.000885 12.45519 2.80187 0.96595 0 0.18985 0.04122 0.16047 0.03485 2.36456 0.13890 1.99863 0.11740 55997.728529 0.000628 6.84015 1.39567 0.95392 0 0.34175 0.06526 0.27926 0.05333 2.33765 0.16809 1.91258 0.13751 55997.729787 0.000631 6.74136 1.38776 0.96789 0 0.34403 0.06641 0.27945 0.05394 2.31925 0.16597 1.87916 0.13445 55997.731124 0.000706 5.23690 0.88483 0.96278 0 0.47213 0.07350 0.38446 0.05985 2.47251 0.16239 2.01566 0.13237
