/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 60056.674173 0.000508 0.48263 0.13278 1.00000 1 1.00568 0.15906 0.47059 0.07441 0.48537 0.10926 0.22714 0.05113 60056.675088 0.000407 0.55915 0.15690 0.96429 1 1.15463 0.19329 0.53148 0.08891 0.64561 0.14540 0.29445 0.06628 60056.676134 0.000639 0.30615 0.07847 1.00000 1 1.27196 0.15933 0.59419 0.07443 0.38942 0.08708 0.18182 0.04066 60056.677368 0.000596 0.39135 0.10086 0.97561 1 1.15214 0.15797 0.53625 0.07352 0.45089 0.09840 0.21000 0.04583 60056.678327 0.000363 0.56653 0.15989 1.00000 1 1.23111 0.21197 0.56459 0.09721 0.69747 0.15596 0.32000 0.07155 60056.679257 0.000566 0.43926 0.11889 1.00000 1 1.00763 0.15367 0.46487 0.07089 0.44262 0.09897 0.20513 0.04587 60056.680186 0.000363 1.08657 0.35583 1.00000 1 0.64229 0.15367 0.29583 0.07077 0.69789 0.15606 0.32000 0.07155 60056.680913 0.000363 0.66191 0.19388 1.00000 1 1.03510 0.19398 0.47917 0.08980 0.68514 0.15424 0.31800 0.07158 60056.681668 0.000392 0.53366 0.14980 1.00000 1 1.21527 0.20621 0.55800 0.09468 0.64854 0.14502 0.29630 0.06625 60056.682699 0.000610 0.73745 0.16393 0.95861 1 1.03259 0.14907 0.46830 0.06759 0.76148 0.12873 0.34773 0.05878
