/* ** ** 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 54422.431408 0.000336 0.17900 0.01401 1.00000 0 23.96733 0.72738 19.06391 0.57830 4.29003 0.30947 3.40673 0.24575 54422.432039 0.000295 0.18708 0.01501 0.99020 0 24.78035 0.77667 20.63098 0.64663 4.63603 0.34252 3.86014 0.28525 54422.432982 0.000648 0.16657 0.00919 0.98040 0 25.97131 0.53621 21.55811 0.44509 4.32602 0.22141 3.59062 0.18377 54422.482336 0.000252 0.18479 0.01433 0.98851 0 27.55153 0.84708 25.06873 0.77075 5.09119 0.36236 4.63806 0.33009 54422.482967 0.000379 0.17353 0.01140 0.99569 0 26.90020 0.68429 24.25904 0.61704 4.66793 0.28281 4.20993 0.25507 54422.500031 0.000486 0.17071 0.01007 0.98818 0 27.88686 0.62560 24.58282 0.55149 4.76055 0.25965 4.19575 0.22885
