/* ** ** 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 56497.014714 0.000804 0.86426 0.27071 0.95683 0 0.58360 0.12284 0.18351 0.03746 0.50438 0.11699 0.14980 0.03369 56497.016497 0.000978 0.63981 0.18533 0.94970 0 0.76460 0.13952 0.19315 0.03521 0.48920 0.11005 0.12414 0.02792 56497.019246 0.001771 0.85090 0.18966 0.95848 0 0.59126 0.08968 0.15185 0.02301 0.50311 0.08216 0.12903 0.02106 56497.023592 0.000435 0.78026 0.28324 0.96602 1 0.53330 0.13097 0.24917 0.06118 0.41612 0.11124 0.19337 0.05168 56497.025099 0.000556 0.45616 0.19772 0.96784 0 0.73223 0.18319 0.18528 0.04632 0.33401 0.11822 0.08625 0.03049
