/* ** ** 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 56271.984640 0.000859 0.73088 0.21516 0.95623 0 0.25849 0.04949 0.19304 0.03696 0.18892 0.04225 0.14108 0.03155 56271.986373 0.000874 0.49154 0.13461 0.97682 0 0.36849 0.05826 0.27632 0.04369 0.18113 0.04050 0.13582 0.03037 56271.988187 0.000940 0.51524 0.13897 0.95077 0 0.35280 0.05593 0.26380 0.04182 0.18178 0.03967 0.13615 0.02971 56271.990259 0.001131 0.45781 0.12391 0.96164 0 0.31156 0.04751 0.23345 0.03560 0.14264 0.03190 0.10656 0.02383 56271.992823 0.001432 0.53223 0.11304 0.96162 0 0.36457 0.04566 0.27058 0.03389 0.19403 0.03328 0.14310 0.02454
