/* ** ** 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 56353.046091 0.000547 11.75517 3.07421 0.95767 0 0.22851 0.05747 0.18658 0.04685 2.68620 0.19255 2.18796 0.15676 56353.047098 0.000460 12.09011 3.24101 0.97484 0 0.25692 0.06634 0.21014 0.05426 3.10623 0.22357 2.54498 0.18315 56353.048047 0.000489 10.52439 2.67232 0.98225 0 0.27452 0.06685 0.22598 0.05504 2.88911 0.20791 2.37634 0.17101 56353.048955 0.000420 12.82196 3.62088 0.99310 0 0.26163 0.07146 0.21508 0.05870 3.35456 0.24069 2.74656 0.19707 56353.049841 0.000466 10.14640 2.50122 0.96894 0 0.30174 0.07112 0.24869 0.05862 3.06155 0.22098 2.52205 0.18203 56353.050793 0.000480 19.46575 6.49737 0.96988 0 0.15410 0.05022 0.12592 0.04101 2.99975 0.21655 2.44372 0.17638 56353.051762 0.000489 6.99439 1.46155 0.97041 0 0.41981 0.08234 0.34268 0.06720 2.93633 0.21163 2.40217 0.17313 56353.052743 0.000492 11.51900 3.00980 0.98235 0 0.25520 0.06411 0.20640 0.05183 2.93966 0.21141 2.37683 0.17092 56353.053715 0.000480 7.97173 1.77859 0.97590 0 0.37479 0.07916 0.30578 0.06457 2.98776 0.21470 2.43820 0.17520 56353.054659 0.000463 14.83406 4.43436 0.96250 0 0.21341 0.06192 0.17369 0.05042 3.16573 0.22749 2.56486 0.18431 56353.055613 0.000492 19.23891 6.23663 0.97059 0 0.15597 0.04933 0.12679 0.04010 3.00075 0.21353 2.42165 0.17230 56353.056866 0.000761 10.28184 1.99772 0.96198 0 0.29787 0.05532 0.24107 0.04476 3.06270 0.17494 2.47722 0.14150
