/* ** ** 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 58793.970837 0.000365 0.13020 0.01016 0.98413 0 27.99889 0.72753 24.14981 0.62745 3.64539 0.26829 3.14265 0.23132 58793.971532 0.000330 0.14282 0.01122 1.00000 0 28.30942 0.77915 23.98055 0.65998 4.04306 0.29759 3.41832 0.25161 58793.972264 0.000402 0.11869 0.00909 0.98561 0 28.89008 0.71632 24.30749 0.60265 3.42899 0.24840 2.88577 0.20903 58793.973007 0.000341 0.14022 0.01064 1.00000 0 28.74518 0.76938 24.22755 0.64844 4.03061 0.28616 3.39695 0.24120 58793.973728 0.000379 0.12887 0.00976 0.99237 0 28.05891 0.72429 23.78059 0.61387 3.61584 0.25740 3.06798 0.21839 58793.974431 0.000324 0.15188 0.01184 1.00000 0 27.19893 0.77117 23.09825 0.65485 4.13098 0.30001 3.51203 0.25506 58793.975137 0.000382 0.12584 0.00955 0.98485 0 28.64472 0.72916 24.40222 0.62116 3.60454 0.25761 3.06931 0.21938 58793.975808 0.000289 0.17151 0.01336 0.99000 0 27.75791 0.82845 23.40729 0.69855 4.76071 0.34264 4.01193 0.28867 58793.976453 0.000356 0.13703 0.01053 0.96748 0 28.97331 0.76499 24.25620 0.64038 3.97031 0.28644 3.32082 0.23956 58793.977209 0.000399 0.12351 0.00966 0.97826 0 27.87805 0.71098 23.36909 0.59597 3.44318 0.25446 2.88786 0.21342 58793.977938 0.000330 0.13995 0.01085 1.00000 0 29.56040 0.80207 24.65424 0.66897 4.13689 0.30044 3.45042 0.25059 58793.978653 0.000385 0.12314 0.00930 0.98496 0 29.72955 0.74425 24.86207 0.62241 3.66087 0.26101 3.06118 0.21824 58793.979440 0.000402 0.11408 0.00890 0.98561 0 29.69732 0.72553 24.82004 0.60636 3.38781 0.25105 2.83108 0.20980
