/* ** ** 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 60055.616027 0.000610 0.49200 0.13454 0.97619 1 1.59430 0.25094 0.39711 0.06250 0.78440 0.17540 0.19512 0.04363 60055.617247 0.000610 0.50407 0.14174 1.00000 1 1.48521 0.24198 0.36929 0.06016 0.74865 0.17157 0.18624 0.04266 60055.618743 0.000886 0.36313 0.09467 0.96721 1 1.51091 0.20249 0.37235 0.04990 0.54866 0.12270 0.13559 0.03032 60055.620370 0.000741 0.32005 0.08406 0.98039 1 1.99050 0.26209 0.49236 0.06483 0.63706 0.14477 0.15763 0.03582 60055.621575 0.000465 0.64979 0.18799 0.96875 1 1.59653 0.29304 0.39802 0.07306 1.03741 0.23198 0.25807 0.05771 60055.623507 0.001467 0.52779 0.10516 0.96432 1 1.23182 0.14603 0.30277 0.03589 0.65015 0.10411 0.16017 0.02565
