/* ** ** 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 58217.287833 0.000576 0.46120 0.12689 0.92462 0 2.19859 0.32930 0.55459 0.07912 1.01399 0.23401 0.21654 0.04871 58217.289005 0.000596 0.44334 0.12085 0.96117 0 2.00148 0.30719 0.45686 0.07000 0.88733 0.19990 0.20123 0.04526 58217.290315 0.000715 0.30870 0.07976 0.97166 0 2.37767 0.30188 0.53783 0.06827 0.73399 0.16516 0.16601 0.03734 58217.291690 0.000660 0.34498 0.09036 0.96930 0 2.34453 0.31446 0.52244 0.07007 0.80882 0.18196 0.18028 0.04055 58217.292905 0.000556 0.44997 0.12369 0.97917 0 2.08845 0.32955 0.47152 0.07435 0.93974 0.21152 0.21193 0.04767 58217.294175 0.000715 0.31310 0.08093 0.96356 0 2.37125 0.30727 0.53716 0.06958 0.74244 0.16605 0.16835 0.03764 58217.295550 0.000654 0.38276 0.10213 0.96903 0 2.09044 0.29994 0.47512 0.06816 0.80014 0.18000 0.18193 0.04092 58217.297286 0.001076 0.40805 0.08135 0.94624 0 2.22411 0.24184 0.50753 0.05516 0.90756 0.15164 0.20740 0.03465
