/* ** ** 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 56049.657340 0.000660 14.86874 4.46094 0.94737 0 0.16497 0.04802 0.12619 0.03673 2.45283 0.17793 1.82407 0.13144 56049.658680 0.000674 11.84828 3.13643 0.94850 0 0.20345 0.05182 0.15091 0.03842 2.41056 0.17378 1.78722 0.12883 56049.660144 0.000790 10.01730 2.47603 0.95604 0 0.20202 0.04778 0.15179 0.03591 2.02369 0.14521 1.51547 0.10873 56049.661663 0.000729 15.58536 4.74785 0.96429 0 0.13991 0.04141 0.10410 0.03079 2.18049 0.15735 1.61928 0.11686 56049.663075 0.000683 14.30170 4.18242 0.98305 0 0.16224 0.04599 0.11986 0.03400 2.32032 0.16655 1.70912 0.12266 56049.664377 0.000619 15.85323 4.71580 0.95794 0 0.16602 0.04793 0.12080 0.03487 2.63189 0.18857 1.93195 0.13841 56049.665726 0.000729 10.96462 2.82926 0.96825 0 0.19684 0.04876 0.14690 0.03636 2.15824 0.15598 1.61054 0.11640 56049.667233 0.000778 12.76347 3.22175 0.97398 0 0.18868 0.04597 0.14014 0.03412 2.40823 0.15872 1.78495 0.11763
