/* ** ** 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 59371.904410 0.000903 0.10766 0.00818 0.98718 0 13.04978 0.30917 11.91586 0.28229 1.40495 0.10137 1.28303 0.09256 59371.906178 0.000865 0.11411 0.00875 0.98997 0 12.79266 0.31460 11.64754 0.28648 1.45978 0.10601 1.32886 0.09651 59371.907963 0.000920 0.10840 0.00834 0.98428 0 12.67067 0.30410 11.53373 0.27683 1.37345 0.10044 1.25083 0.09146 59371.909757 0.000874 0.12065 0.00928 0.97351 0 12.16657 0.30642 11.09248 0.27931 1.46792 0.10663 1.33790 0.09717 59371.911453 0.000822 0.12089 0.00918 0.99296 0 12.66157 0.31900 11.64537 0.29340 1.53070 0.10969 1.40782 0.10088 59371.912720 0.000446 0.09120 0.01081 0.99351 0 12.69360 0.44025 11.64766 0.40403 1.15769 0.13122 1.06284 0.12048
