/* ** ** 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 54916.950847 0.000440 0.18599 0.01455 0.97368 0 16.90106 0.51578 14.33107 0.43732 3.14338 0.22647 2.66817 0.19222 54916.951779 0.000492 0.17063 0.01308 0.97059 0 16.89853 0.48969 14.32018 0.41495 2.88336 0.20460 2.44370 0.17341 54916.952702 0.000431 0.19058 0.01509 0.99329 0 16.42123 0.51529 13.96402 0.43820 3.12960 0.22749 2.65828 0.19317 54916.953579 0.000446 0.19740 0.01549 0.98052 0 15.57659 0.49151 13.31530 0.42015 3.07480 0.22094 2.62843 0.18887 54916.954496 0.000472 0.17508 0.01351 1.00000 0 16.48630 0.49242 14.05048 0.41966 2.88645 0.20537 2.46139 0.17511 54916.955503 0.000535 0.15130 0.01166 0.98919 0 16.86367 0.46679 14.36926 0.39771 2.55144 0.18355 2.17344 0.15636 54916.956516 0.000477 0.17367 0.01365 0.98182 0 16.51320 0.49169 14.00975 0.41712 2.86777 0.20858 2.43379 0.17706 54916.957441 0.000448 0.18936 0.01497 0.98710 0 15.89111 0.49529 13.57807 0.42320 3.00916 0.21867 2.57141 0.18686 54916.958385 0.000495 0.17334 0.01336 0.97661 0 16.10351 0.47417 13.76139 0.40520 2.79131 0.19885 2.38537 0.16993 54916.959389 0.000509 0.16417 0.01286 0.97727 0 16.22353 0.46781 13.86089 0.39968 2.66337 0.19405 2.27571 0.16581 54916.960847 0.000949 0.17483 0.00969 0.98780 0 16.07786 0.34167 13.73613 0.29191 2.81094 0.14396 2.40144 0.12299
