/* ** ** 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 58242.546209 0.000741 0.59741 0.16972 1.00000 1 0.33713 0.05907 0.26240 0.04597 0.20140 0.04504 0.15686 0.03508 58242.547865 0.000915 0.41441 0.11087 0.98413 1 0.39614 0.05818 0.31133 0.04572 0.16416 0.03671 0.12903 0.02885 58242.549652 0.000872 0.41649 0.11161 1.00000 1 0.40453 0.05901 0.31865 0.04648 0.16848 0.03787 0.13266 0.02982 58242.551351 0.000828 0.46285 0.12584 0.96491 1 0.39810 0.06086 0.31200 0.04770 0.18426 0.04143 0.14473 0.03253 58242.553515 0.001336 0.42849 0.09605 0.98535 1 0.37792 0.04667 0.29689 0.03666 0.16194 0.03029 0.12708 0.02377 58243.458494 0.001191 0.32267 0.08334 1.00000 1 0.39932 0.05157 0.30380 0.03922 0.12885 0.02882 0.09756 0.02182 58243.460353 0.000668 0.68049 0.19501 0.97826 1 0.37027 0.06876 0.27619 0.05129 0.25197 0.05499 0.18667 0.04073 58243.461936 0.000915 0.50871 0.14018 1.00000 1 0.33494 0.05393 0.25028 0.04030 0.17039 0.03810 0.12698 0.02839 58243.464042 0.001191 0.37113 0.09503 0.98780 1 0.37469 0.05017 0.27948 0.03742 0.13906 0.03035 0.10370 0.02263
