/* ** ** 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 57263.790071 0.000857 0.54270 0.14999 0.98305 1 0.36550 0.05932 0.25763 0.04179 0.19836 0.04437 0.13793 0.03084 57263.792337 0.001409 0.74354 0.16426 0.97765 1 0.29893 0.04334 0.20376 0.02954 0.22227 0.03705 0.15185 0.02531 57263.871287 0.000654 0.66939 0.19405 0.97778 1 0.37689 0.06887 0.27273 0.04979 0.25229 0.05678 0.18090 0.04067 57263.872594 0.000654 0.55621 0.15593 0.97778 1 0.45864 0.07753 0.32558 0.05503 0.25510 0.05705 0.18182 0.04066 57263.874105 0.000857 0.51347 0.14136 0.94915 1 0.39562 0.06353 0.27785 0.04461 0.20314 0.04543 0.14286 0.03194 57263.876008 0.001046 0.85739 0.18900 0.98528 1 0.37054 0.05613 0.25764 0.03903 0.31770 0.05088 0.21990 0.03521
