/* ** ** 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 60106.930870 0.000353 0.16940 0.01317 0.99180 0 21.84197 0.64180 19.33962 0.56824 3.70007 0.26625 3.27717 0.23582 60106.931555 0.000333 0.17532 0.01360 0.99130 0 22.63100 0.68207 19.99024 0.60244 3.96766 0.28364 3.50673 0.25069 60106.932273 0.000385 0.14848 0.01169 1.00000 0 22.01637 0.61575 19.66876 0.55009 3.26889 0.24067 2.92031 0.21500 60106.933051 0.000394 0.14963 0.01149 1.00000 0 21.98294 0.61146 19.51272 0.54273 3.28940 0.23540 2.91902 0.20890 60106.933827 0.000382 0.16200 0.01260 0.99242 0 20.91189 0.60769 18.56554 0.53951 3.38770 0.24445 3.01171 0.21728 60106.934614 0.000405 0.14449 0.01120 0.99286 0 22.03914 0.60168 19.63182 0.53596 3.18449 0.23100 2.83514 0.20566 60106.935436 0.000417 0.14867 0.01137 1.00000 0 20.82816 0.57690 18.60008 0.51519 3.09660 0.22072 2.76537 0.19711 60106.936266 0.000414 0.15285 0.01179 0.99301 0 20.42365 0.57392 18.23412 0.51240 3.12185 0.22432 2.78704 0.20026 60106.937076 0.000396 0.16775 0.01306 0.97080 0 19.80969 0.57806 17.68337 0.51601 3.32316 0.23975 2.96642 0.21401 60106.937837 0.000365 0.16322 0.01265 1.00000 0 21.55677 0.62718 19.24408 0.55990 3.51851 0.25282 3.14095 0.22569 60106.938671 0.000469 0.12846 0.01004 1.00000 0 20.94872 0.54354 18.70165 0.48524 2.69100 0.19839 2.40233 0.17711 60106.939715 0.000576 0.17578 0.01075 0.97862 0 20.93495 0.49199 18.68711 0.43916 3.67991 0.20783 3.28489 0.18552 60106.997647 0.000689 0.17810 0.00982 0.98739 0 21.26711 0.45892 18.81864 0.40607 3.78774 0.19228 3.35259 0.17017
