/* ** ** 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 56778.050138 0.000373 0.12268 0.00936 1.00000 0 27.25601 0.68310 25.09178 0.62882 3.34375 0.24086 3.07749 0.22163 56778.050858 0.000347 0.14060 0.01071 1.00000 0 25.80377 0.69610 23.61737 0.63711 3.62813 0.25840 3.32313 0.23662 56778.051529 0.000324 0.14684 0.01120 0.99107 0 26.45531 0.72386 24.46621 0.66943 3.88464 0.27660 3.59257 0.25581 56778.052178 0.000324 0.14083 0.01083 1.00000 0 27.20712 0.73334 25.16907 0.67840 3.83161 0.27594 3.54461 0.25527 56778.052849 0.000347 0.14142 0.01081 0.99167 0 25.61506 0.69018 23.70249 0.63864 3.62252 0.25908 3.35200 0.23973 56778.053529 0.000333 0.14297 0.01093 0.99130 0 26.45556 0.71494 24.47454 0.66141 3.78228 0.27050 3.49901 0.25024 56778.054371 0.000509 0.15133 0.00936 0.98221 0 26.29306 0.57578 24.32348 0.53265 3.97890 0.23024 3.68077 0.21299 56778.928107 0.000567 0.11148 0.00854 0.98980 0 21.76601 0.52419 18.14916 0.43682 2.42652 0.17642 2.02686 0.14730 56778.929169 0.000495 0.12405 0.00949 1.00000 0 21.80051 0.55517 18.62545 0.47432 2.70441 0.19518 2.31038 0.16675 56778.930155 0.000492 0.12650 0.00968 0.98824 0 21.92671 0.56010 18.60444 0.47522 2.77363 0.20018 2.35163 0.16973 56778.931131 0.000483 0.12175 0.00925 1.00000 0 22.98014 0.57666 19.52865 0.49002 2.79784 0.20055 2.37688 0.17038 56778.932117 0.000503 0.12326 0.00944 1.00000 0 22.10303 0.55386 18.80876 0.47132 2.72434 0.19709 2.31900 0.16771
