/* ** ** 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 58578.247300 0.000391 0.48714 0.08657 0.97037 0 2.39590 0.25194 1.56721 0.16462 1.16713 0.16719 0.76420 0.10949 58578.248183 0.000492 0.33461 0.05584 0.98824 0 2.54862 0.21531 1.75799 0.14850 0.85280 0.12274 0.58703 0.08449 58578.249184 0.000509 0.36093 0.06016 0.97727 0 2.31688 0.20129 1.60335 0.13927 0.83622 0.11895 0.57937 0.08241 58578.250144 0.000451 0.44598 0.07753 0.98718 0 2.07102 0.20450 1.44320 0.14251 0.92363 0.13215 0.64375 0.09211 58578.251108 0.000512 0.37148 0.06261 0.96045 0 2.25880 0.19794 1.56318 0.13696 0.83910 0.12080 0.58013 0.08349 58578.252045 0.000425 0.37046 0.06219 0.99320 0 2.67939 0.24234 1.84762 0.16709 0.99260 0.14039 0.68607 0.09703 58578.253003 0.000532 0.35851 0.05955 0.95109 0 2.29698 0.19701 1.59116 0.13645 0.82350 0.11714 0.56944 0.08100 58578.254045 0.000509 0.39852 0.06754 0.98864 0 2.06802 0.19049 1.43914 0.13257 0.82415 0.11723 0.57271 0.08147 58578.254927 0.000373 0.50306 0.08862 0.97674 0 2.24732 0.23350 1.57430 0.16357 1.13054 0.16082 0.79089 0.11250 58578.255816 0.000515 0.35643 0.05998 0.96067 0 2.34810 0.20474 1.61767 0.14102 0.83694 0.12047 0.57674 0.08300 58578.256970 0.000639 0.39779 0.05564 0.97738 0 2.44016 0.18501 1.69382 0.12841 0.97068 0.11408 0.67467 0.07928
