/* ** ** 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 58222.267859 0.000498 0.43033 0.07325 0.98837 0 1.67328 0.15835 1.36699 0.12933 0.72007 0.10188 0.58922 0.08333 58222.268834 0.000477 0.34182 0.05653 0.97576 0 2.20816 0.18620 1.80975 0.15256 0.75479 0.10738 0.61889 0.08805 58222.269659 0.000347 0.49202 0.08606 0.99167 0 2.07138 0.21070 1.70631 0.17357 1.01917 0.14502 0.83732 0.11912 58222.270489 0.000483 0.46406 0.08058 0.98204 0 1.59374 0.15672 1.30370 0.12816 0.73960 0.10585 0.60436 0.08650 58222.271479 0.000506 0.35915 0.05995 0.98857 0 1.98026 0.17293 1.60235 0.13993 0.71121 0.10119 0.57596 0.08194 58222.272483 0.000498 0.38747 0.06523 0.95930 0 1.90061 0.16845 1.54899 0.13729 0.73642 0.10540 0.60069 0.08597 58222.273415 0.000434 0.50352 0.08816 0.94000 0 1.71358 0.17273 1.39710 0.14079 0.86282 0.12353 0.70294 0.10060 58222.274286 0.000437 0.34791 0.05732 0.96689 0 2.42369 0.20484 1.97115 0.16656 0.84322 0.11926 0.68607 0.09703 58222.275226 0.000503 0.37028 0.06240 0.97701 0 1.95965 0.17442 1.57314 0.14002 0.72561 0.10384 0.58303 0.08344 58222.276074 0.000344 0.64533 0.11314 0.94958 0 1.88557 0.20909 1.51421 0.16791 1.21681 0.16525 0.97883 0.13291 58222.276803 0.000385 0.42778 0.07372 0.98496 0 2.16694 0.20525 1.76144 0.16684 0.92698 0.13346 0.75258 0.10836 58222.278175 0.000987 0.38450 0.04640 0.97361 0 1.89477 0.12202 1.53087 0.09857 0.72855 0.07434 0.58946 0.06014
