/* ** ** 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 57511.931927 0.000469 0.13791 0.01049 0.98148 0 20.28327 0.53431 18.14443 0.47795 2.79733 0.19965 2.50267 0.17860 57511.932818 0.000422 0.15206 0.01171 0.97945 0 20.19597 0.55931 18.26551 0.50585 3.07108 0.22063 2.77751 0.19954 57511.933729 0.000489 0.13095 0.01017 0.98817 0 19.79663 0.51333 17.91195 0.46446 2.59230 0.18972 2.34549 0.17165 57511.934748 0.000530 0.12814 0.00987 0.97814 0 18.91642 0.48282 17.10937 0.43670 2.42398 0.17622 2.19239 0.15939 57511.935729 0.000451 0.14078 0.01078 0.99359 0 20.15822 0.54097 18.16870 0.48756 2.83781 0.20346 2.55840 0.18342 57511.936733 0.000553 0.11954 0.00910 0.97906 0 19.58538 0.48119 17.66146 0.43390 2.34125 0.16863 2.11326 0.15221 57511.937766 0.000480 0.13571 0.01041 1.00000 0 19.39209 0.51262 17.54174 0.46370 2.63160 0.18955 2.38061 0.17147 57511.938724 0.000477 0.13400 0.01022 0.98788 0 20.14606 0.52508 18.14953 0.47304 2.69947 0.19353 2.43284 0.17442 57511.939707 0.000506 0.13308 0.01030 0.99429 0 18.76177 0.49244 16.97431 0.44552 2.49688 0.18189 2.25902 0.16456 57511.940674 0.000460 0.14231 0.01075 0.98113 0 19.95119 0.53180 18.04795 0.48107 2.83925 0.20077 2.56838 0.18161 57511.941646 0.000512 0.13463 0.01032 0.97740 0 18.80473 0.49217 16.95093 0.44366 2.53170 0.18237 2.28428 0.16453
