/* ** ** Swift/XRT hardness ratio for 3C 279. ** 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 54972.786835 0.001307 0.74160 0.21410 0.97778 1 0.15896 0.03004 0.12874 0.02433 0.11788 0.02573 0.09545 0.02083 54972.790248 0.002106 0.37632 0.09403 0.94998 1 0.20938 0.02690 0.16917 0.02174 0.07879 0.01688 0.06359 0.01362 54972.853243 0.001743 0.30661 0.07642 0.98333 1 0.28332 0.03411 0.23193 0.02792 0.08687 0.01896 0.07119 0.01553 54972.857005 0.002019 0.48527 0.11854 0.88297 1 0.20517 0.02851 0.16778 0.02331 0.09956 0.02000 0.08115 0.01630 54972.918446 0.001670 0.33611 0.08751 0.99130 1 0.25189 0.03308 0.20714 0.02720 0.08466 0.01903 0.06982 0.01570 54972.921133 0.001017 0.43836 0.11781 0.97143 1 0.32649 0.04867 0.26866 0.04005 0.14312 0.03200 0.11765 0.02631 54972.923922 0.001772 0.42686 0.10187 0.96759 1 0.24101 0.03138 0.19832 0.02582 0.10288 0.02058 0.08471 0.01694
