/* ** ** 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 54952.965234 0.000498 0.15453 0.01177 0.99419 0 16.45977 0.45770 15.19383 0.42248 2.54356 0.18032 2.34633 0.16631 54952.966194 0.000463 0.17082 0.01349 0.98125 0 15.69825 0.46598 14.56150 0.43224 2.68163 0.19631 2.48746 0.18210 54952.967111 0.000454 0.16461 0.01284 1.00000 0 16.49344 0.48181 15.30027 0.44696 2.71506 0.19627 2.51866 0.18208 54952.968089 0.000524 0.15553 0.01182 0.97790 0 15.95448 0.44306 14.65144 0.40686 2.48139 0.17545 2.27811 0.16107 54952.969117 0.000503 0.14798 0.01148 0.98276 0 16.83027 0.46358 15.54661 0.42822 2.49050 0.18054 2.30074 0.16676 54952.970098 0.000477 0.16629 0.01273 0.99394 0 16.20910 0.46937 14.82605 0.42926 2.69542 0.19107 2.46208 0.17449 54952.971073 0.000498 0.16166 0.01269 0.98256 0 15.54327 0.44742 14.36818 0.41360 2.51273 0.18344 2.32269 0.16958 54952.972042 0.000472 0.15912 0.01241 0.99387 0 16.57075 0.47525 15.26192 0.43771 2.63671 0.19119 2.42856 0.17602 54952.972956 0.000443 0.17185 0.01329 0.99346 0 16.49372 0.49022 15.24305 0.45302 2.83439 0.20244 2.61691 0.18688 54952.973920 0.000521 0.14701 0.01155 0.98333 0 16.18589 0.44573 14.96522 0.41210 2.37954 0.17506 2.19821 0.16173 54952.975398 0.000958 0.14075 0.00806 0.99094 0 16.94251 0.33696 15.57329 0.30971 2.38460 0.12807 2.19128 0.11768
