/* ** ** 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 59266.088004 0.000689 0.15293 0.01169 0.99160 0 12.01428 0.33640 11.06095 0.30971 1.83737 0.13069 1.69084 0.12025 59266.089586 0.000894 0.12267 0.00934 0.98058 0 11.45303 0.28575 10.64718 0.26563 1.40492 0.10107 1.30622 0.09396 59266.091163 0.000683 0.14927 0.01158 0.99576 0 12.12450 0.33896 11.23625 0.31413 1.80979 0.13096 1.67726 0.12135 59266.092599 0.000752 0.14846 0.01163 0.98846 0 11.04731 0.30799 10.24001 0.28548 1.64010 0.12003 1.52101 0.11133 59266.094181 0.000830 0.12975 0.01007 0.97909 0 11.56280 0.29850 10.72370 0.27683 1.50030 0.10980 1.39110 0.10182 59266.096106 0.001094 0.13699 0.00919 0.97619 0 11.13510 0.25536 10.35775 0.23751 1.52545 0.09621 1.41869 0.08948
