/* ** ** 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 55168.643011 0.000935 0.57323 0.05147 0.97833 0 2.58629 0.14025 2.19061 0.11878 1.48254 0.10608 1.25462 0.08977 55168.644773 0.000828 0.66706 0.06150 0.95804 0 2.52940 0.14648 2.16422 0.12533 1.68727 0.12104 1.44352 0.10355 55168.646460 0.000859 0.63584 0.05796 0.96970 0 2.53877 0.14402 2.17039 0.12313 1.61425 0.11519 1.37984 0.09847 55168.648144 0.000825 0.69573 0.06482 0.97193 0 2.41017 0.14411 2.05974 0.12316 1.67684 0.11982 1.43295 0.10239 55168.649843 0.000874 0.63346 0.05764 0.97351 0 2.50440 0.14196 2.13892 0.12125 1.58643 0.11291 1.35486 0.09643 55168.652091 0.001374 0.62209 0.04703 0.97053 0 2.36066 0.11000 2.01367 0.09383 1.46854 0.08742 1.25197 0.07453
