/* ** ** 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 55959.563882 0.000703 8.33567 1.83594 0.97531 0 0.24215 0.05050 0.20388 0.04251 2.01849 0.14312 1.70063 0.12057 55959.565346 0.000761 10.67099 2.70968 0.96958 0 0.17106 0.04167 0.14533 0.03540 1.82540 0.13098 1.55092 0.11129 55959.566798 0.000692 10.73992 2.71806 0.97071 0 0.18565 0.04503 0.15767 0.03824 1.99387 0.14414 1.69350 0.12242 55959.568179 0.000689 14.63562 4.37725 0.98739 0 0.13579 0.03943 0.11524 0.03346 1.98744 0.14267 1.68702 0.12110 55959.569611 0.000744 10.73352 2.68416 0.95720 0 0.17667 0.04233 0.14996 0.03593 1.89630 0.13587 1.60976 0.11534 55959.570962 0.000608 11.31372 2.90659 0.96667 0 0.20332 0.05017 0.17288 0.04266 2.30031 0.16434 1.95585 0.13973 55959.572365 0.000796 7.79633 1.69432 0.95636 0 0.22911 0.04704 0.19460 0.03995 1.78622 0.12728 1.51727 0.10812 55959.574090 0.000929 13.83358 3.43558 0.96659 0 0.14350 0.03450 0.12158 0.02923 1.98510 0.12364 1.68305 0.10483 55959.697543 0.001036 7.60801 1.51171 0.97765 0 0.30102 0.05621 0.17188 0.03192 2.29019 0.15554 1.27304 0.08598
