/* ** ** 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 55520.636828 0.000891 0.68656 0.06329 0.96753 0 2.27229 0.13302 1.95311 0.11433 1.56006 0.11110 1.34000 0.09542 55520.638637 0.000917 0.62897 0.05763 0.96845 0 2.38685 0.13570 2.04677 0.11635 1.50124 0.10786 1.28692 0.09246 55520.640500 0.000946 0.59562 0.05331 0.97248 0 2.46482 0.13474 2.11736 0.11574 1.46811 0.10406 1.26099 0.08937 55520.642245 0.000799 0.65306 0.06028 0.98551 0 2.59392 0.15066 2.22673 0.12932 1.69399 0.12153 1.45457 0.10434 55520.643941 0.000897 0.60748 0.05543 0.99677 0 2.44698 0.13772 2.11752 0.11918 1.48648 0.10676 1.28614 0.09237 55520.646371 0.001534 0.59570 0.04130 0.97925 0 2.52768 0.10736 2.17549 0.09240 1.50574 0.08253 1.29607 0.07103
