/* ** ** 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 55722.059694 0.000984 0.13416 0.01029 0.98529 0 9.72989 0.25394 8.80131 0.22970 1.30533 0.09417 1.18074 0.08516 55722.060973 0.000295 0.10869 0.01640 0.99020 0 10.03163 0.47445 9.03312 0.42718 1.09036 0.15624 0.98168 0.14062 55722.062327 0.001059 0.12938 0.00981 0.98907 0 9.36818 0.24008 8.48946 0.21756 1.21207 0.08653 1.09838 0.07841 55722.063763 0.000376 0.11180 0.01511 0.96154 0 9.76429 0.41405 8.81128 0.37364 1.09168 0.14008 0.98551 0.12646 55722.064448 0.000310 0.11191 0.01672 0.98131 0 9.57049 0.45141 8.62623 0.40681 1.07107 0.15186 0.96336 0.13660 55722.065082 0.000324 0.10735 0.01619 0.99107 0 9.17951 0.43374 8.32122 0.39319 0.98546 0.14116 0.89324 0.12795 55722.066274 0.000862 0.15132 0.01155 0.97651 0 10.03998 0.27661 9.06089 0.24961 1.51929 0.10812 1.36987 0.09748 55722.067449 0.000312 0.10545 0.01626 0.98148 0 9.63537 0.44956 8.68648 0.40527 1.01609 0.14933 0.91617 0.13467 55722.069275 0.001513 0.13251 0.00816 0.97132 0 10.01807 0.20809 9.07703 0.18855 1.32748 0.07697 1.20248 0.06972
