/* ** ** 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 58253.154771 0.000367 0.49059 0.08530 0.97638 0 1.95240 0.19525 1.63791 0.16380 0.95782 0.13625 0.80364 0.11432 58253.155564 0.000425 0.40460 0.06860 0.99320 0 1.99414 0.18392 1.68528 0.15544 0.80683 0.11479 0.68254 0.09709 58253.156339 0.000350 0.75325 0.14187 0.94215 0 1.35393 0.16582 1.15397 0.14130 1.01985 0.14592 0.86961 0.12443 58253.157103 0.000414 0.52856 0.09351 0.99301 0 1.56866 0.16457 1.34057 0.14064 0.82914 0.11812 0.70862 0.10095 58253.157899 0.000382 0.54811 0.09728 0.96970 0 1.66222 0.17645 1.42035 0.15078 0.91108 0.12960 0.77853 0.11074 58253.158619 0.000339 0.51256 0.09147 0.98291 0 1.96280 0.20707 1.67277 0.17646 1.00606 0.14481 0.85757 0.12342 58253.159351 0.000394 0.47630 0.08244 0.97794 0 1.84275 0.18173 1.57057 0.15487 0.87770 0.12485 0.74926 0.10658 58253.160184 0.000440 0.33528 0.05501 0.94737 0 2.41561 0.19754 2.06406 0.16879 0.80990 0.11521 0.69202 0.09844 58253.160974 0.000350 0.48863 0.08406 0.97521 0 2.07365 0.20724 1.77188 0.17708 1.01325 0.14188 0.86585 0.12124 58253.161683 0.000359 0.49535 0.08770 0.97581 0 1.91537 0.19522 1.63681 0.16682 0.94878 0.13736 0.81078 0.11738 58253.162424 0.000382 0.51548 0.08973 0.96970 0 1.78595 0.18122 1.52120 0.15436 0.92063 0.13020 0.78255 0.11067 58253.163228 0.000422 0.44152 0.07689 0.98630 0 1.81925 0.17602 1.53807 0.14880 0.80323 0.11631 0.68128 0.09863 58253.164047 0.000396 0.49034 0.08798 0.98540 0 1.72309 0.17841 1.46345 0.15151 0.84491 0.12381 0.71906 0.10535 58253.164878 0.000434 0.45143 0.07818 0.96667 0 1.78935 0.17403 1.52939 0.14874 0.80777 0.11574 0.69040 0.09892 58253.165986 0.000674 0.38151 0.05267 0.96996 0 2.03487 0.14931 1.73473 0.12729 0.77631 0.09078 0.66228 0.07745
