/* ** ** 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 54966.080073 0.001307 0.38546 0.10150 0.97778 1 0.30374 0.04222 0.23590 0.03278 0.11708 0.02619 0.09091 0.02033 54966.082571 0.001191 0.50306 0.13850 0.97561 1 0.25518 0.04098 0.19948 0.03203 0.12837 0.02871 0.10000 0.02236 54966.084866 0.001104 0.57928 0.16173 0.94737 1 0.24409 0.04080 0.19146 0.03200 0.14139 0.03162 0.11111 0.02485 54966.088120 0.002150 0.31461 0.07078 0.99037 1 0.28644 0.03156 0.22567 0.02487 0.09012 0.01767 0.07095 0.01392 54966.149518 0.001322 0.47366 0.12920 0.98901 1 0.24208 0.03781 0.18851 0.02944 0.11466 0.02564 0.08889 0.01988 54966.152379 0.001540 0.32790 0.08474 1.00000 1 0.29319 0.03799 0.22998 0.02980 0.09614 0.02150 0.07547 0.01688 54966.155415 0.001496 0.47443 0.11118 0.98817 1 0.28585 0.03822 0.22372 0.02991 0.13561 0.02610 0.10611 0.02042
