/* ** ** 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 56056.216503 0.000940 0.42563 0.03616 0.96000 0 3.49960 0.16087 2.99560 0.13770 1.48953 0.10641 1.27617 0.09116 56056.218312 0.000868 0.43788 0.03757 0.99667 0 3.54269 0.16950 3.04129 0.14551 1.55128 0.11047 1.33166 0.09483 56056.220198 0.001019 0.39931 0.03389 0.98295 0 3.37455 0.15312 2.86046 0.12979 1.34750 0.09665 1.14353 0.08201 56056.222189 0.000972 0.42506 0.03619 0.97619 0 3.34211 0.15531 2.85782 0.13280 1.42061 0.10133 1.21545 0.08670 56056.224090 0.000929 0.43750 0.03733 0.96573 0 3.43054 0.16063 2.93890 0.13761 1.50086 0.10706 1.28602 0.09173 56056.226046 0.001021 0.40342 0.03370 0.96884 0 3.42909 0.15297 2.94730 0.13148 1.38338 0.09769 1.18912 0.08397
