/* ** ** 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 54119.223881 0.001118 0.34414 0.08924 1.00000 1 0.36899 0.04846 0.30130 0.03956 0.12699 0.02840 0.10390 0.02323 54119.225929 0.000930 0.41764 0.11232 1.00000 1 0.36419 0.05442 0.29932 0.04473 0.15210 0.03401 0.12500 0.02795 54119.227760 0.000901 0.42292 0.11366 1.00000 1 0.37118 0.05533 0.30509 0.04548 0.15698 0.03510 0.12903 0.02885 54119.229735 0.001075 0.36856 0.09683 1.00000 1 0.35683 0.04921 0.29332 0.04045 0.13152 0.02941 0.10811 0.02417 54119.231870 0.001060 0.55136 0.15139 1.00000 1 0.25390 0.04232 0.20870 0.03478 0.13999 0.03055 0.11507 0.02511 54119.233526 0.000596 0.76307 0.22936 0.97561 1 0.31886 0.06405 0.26209 0.05264 0.24331 0.05441 0.20000 0.04472 54119.235008 0.000886 0.47463 0.12964 0.98361 1 0.34033 0.05278 0.27864 0.04322 0.16153 0.03632 0.13266 0.02982 54119.236794 0.000901 0.54508 0.15254 1.00000 1 0.28761 0.04794 0.23607 0.03934 0.15677 0.03524 0.12838 0.02886 54119.239307 0.001612 0.48716 0.10659 0.96888 1 0.29635 0.03796 0.24353 0.03120 0.14437 0.02561 0.11864 0.02104
