/* ** ** Swift/XRT hardness ratio for 3C 454.3. ** 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 54744.549620 0.001060 0.74967 0.16158 0.99892 1 0.59403 0.08533 0.28296 0.04064 0.44532 0.07156 0.21325 0.03426 54744.650316 0.034390 0.55941 0.10252 0.05063 1 0.58077 0.06378 0.27862 0.03059 0.32489 0.04767 0.15599 0.02288 54744.750663 0.000712 0.42880 0.10545 0.99892 1 0.93367 0.12802 0.45689 0.06263 0.40036 0.08173 0.19612 0.04003 54744.817676 0.001060 0.49357 0.11218 0.94413 1 0.70927 0.09356 0.35041 0.04622 0.35008 0.06479 0.17194 0.03181 54744.884696 0.001409 0.47504 0.10585 0.97831 1 0.54141 0.06851 0.26449 0.03346 0.25719 0.04717 0.12592 0.02309 54744.951701 0.001060 0.49957 0.12010 0.96150 1 0.61675 0.08575 0.29641 0.04121 0.30811 0.06043 0.14816 0.02906
