/* ** ** 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 55139.737157 0.000590 0.50926 0.08909 0.98529 0 1.13515 0.11549 0.97615 0.09931 0.57809 0.08226 0.49570 0.07053 55139.738326 0.000579 0.60821 0.10130 0.97252 0 1.14782 0.11728 0.98853 0.10099 0.69811 0.09182 0.60223 0.07921 55139.805617 0.000295 0.40127 0.10833 0.99020 0 1.13862 0.16610 0.97068 0.14159 0.45689 0.10379 0.39133 0.08887 55139.806786 0.000874 0.57122 0.08196 0.97187 0 1.07234 0.09349 0.91977 0.08019 0.61254 0.06981 0.52557 0.05989 55139.874625 0.000553 0.55944 0.09994 0.96859 0 1.11430 0.11896 0.95774 0.10225 0.62339 0.08929 0.53542 0.07669 55139.875788 0.000611 0.57709 0.09966 0.98753 0 1.05869 0.11146 0.89631 0.09435 0.61096 0.08364 0.51650 0.07070 55139.938414 0.001155 0.44591 0.05503 0.96491 0 1.30124 0.08883 1.12071 0.07650 0.58024 0.05966 0.49921 0.05132
