/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 55533.517205 0.000778 0.14276 0.01141 0.98141 0 20.19698 0.56149 10.49147 0.28723 2.88342 0.21604 1.47014 0.10881 55533.518677 0.000694 0.15360 0.01186 0.97917 0 19.42219 0.54576 11.01366 0.30928 2.98327 0.21460 1.69060 0.12158 55533.519971 0.000599 0.16073 0.01239 0.98551 0 21.53270 0.62112 12.16531 0.35043 3.46094 0.24746 1.95630 0.13978 55533.521261 0.000692 0.14075 0.01068 0.98745 0 21.45953 0.57494 12.07578 0.32350 3.02048 0.21447 1.69863 0.12059 55533.522650 0.000697 0.13699 0.01050 0.99170 0 21.02192 0.55826 12.10345 0.32136 2.87982 0.20716 1.66231 0.11955 55533.524004 0.000657 0.15529 0.01198 0.96916 0 20.01192 0.56117 11.62480 0.32575 3.10760 0.22341 1.80587 0.12987 55533.525251 0.000590 0.15849 0.01222 0.97059 0 21.53767 0.61452 12.65519 0.36103 3.41354 0.24455 2.00546 0.14366 55533.526548 0.000706 0.13688 0.01056 0.97541 0 20.58930 0.54876 12.14534 0.32363 2.81825 0.20409 1.66176 0.12028 55533.527963 0.000709 0.13791 0.01060 0.98367 0 20.14959 0.53558 11.92404 0.31689 2.77892 0.20040 1.64020 0.11826 55533.529950 0.001279 0.14708 0.00850 0.98416 0 19.10431 0.39418 11.08822 0.22876 2.80980 0.15160 1.63369 0.08818
