/* ** ** 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 54311.458242 0.000479 1.42049 0.49661 1.00000 1 0.67856 0.18136 0.16969 0.04535 0.96390 0.21722 0.24065 0.05424 54311.459913 0.001191 0.65534 0.14560 0.98630 1 1.03256 0.14406 0.25894 0.03613 0.67667 0.11700 0.16949 0.02930 54311.524980 0.000421 0.62906 0.17780 1.00000 1 0.99139 0.17807 0.45925 0.08248 0.62365 0.13610 0.28965 0.06321 54311.525779 0.000378 0.54735 0.15141 0.96154 1 1.23619 0.20336 0.60009 0.09871 0.67663 0.15048 0.33007 0.07340 54311.526447 0.000291 0.95957 0.30964 1.00000 1 0.84643 0.19692 0.41673 0.09694 0.81221 0.18162 0.39999 0.08944 54311.559735 0.032998 0.66166 0.12325 0.03780 1 1.07241 0.12958 0.36471 0.04180 0.70957 0.10059 0.25967 0.03486 54311.593910 0.001177 0.53788 0.12171 0.92593 1 1.18579 0.15697 0.29523 0.03908 0.63781 0.11706 0.15923 0.02922
