/* ** ** 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 59314.143526 0.000558 0.13460 0.01040 0.97927 0 17.00885 0.44691 15.45824 0.40613 2.28946 0.16631 2.08093 0.15117 59314.144625 0.000541 0.13688 0.01035 0.98396 0 17.65748 0.46510 15.97198 0.42065 2.41703 0.17123 2.18930 0.15507 59314.145722 0.000556 0.13391 0.01040 0.98958 0 16.92158 0.45080 15.46492 0.41199 2.26589 0.16528 2.07082 0.15105 59314.146879 0.000602 0.12400 0.00949 0.99519 0 17.07898 0.43588 15.37324 0.39231 2.11788 0.15282 1.90888 0.13773 59314.148037 0.000556 0.14379 0.01112 0.96354 0 16.32661 0.44122 14.86497 0.40169 2.34757 0.17011 2.13675 0.15481 59314.149157 0.000564 0.13197 0.01008 1.00000 0 17.10345 0.44953 15.42941 0.40548 2.25716 0.16183 2.03580 0.14590 59314.150326 0.000605 0.12044 0.00926 0.99522 0 17.30970 0.43721 15.68844 0.39623 2.08481 0.15143 1.89084 0.13736 59314.151564 0.000634 0.11362 0.00910 0.98174 0 17.25885 0.42882 15.58541 0.38718 1.96092 0.14938 1.76928 0.13481 59314.152814 0.000616 0.15793 0.01094 0.98592 0 16.78417 0.43148 15.13049 0.38882 2.65074 0.17043 2.38874 0.15360
