/* ** ** 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 56753.322911 0.001191 0.39000 0.10232 0.95122 1 0.55411 0.07597 0.26487 0.03630 0.21610 0.04834 0.10256 0.02293 56753.324857 0.000755 0.80634 0.24719 1.00000 1 0.39592 0.08302 0.19066 0.03998 0.31924 0.07139 0.15385 0.03440 56753.326440 0.000828 0.47229 0.12906 0.98246 1 0.62175 0.09626 0.29913 0.04630 0.29365 0.06612 0.14199 0.03196 56753.328082 0.000813 0.58543 0.16942 1.00000 1 0.50026 0.08915 0.23968 0.04271 0.29287 0.06678 0.14025 0.03198 56753.329679 0.000784 0.66595 0.19359 0.98148 1 0.46532 0.08642 0.22745 0.04224 0.30988 0.06930 0.15094 0.03375 56753.331887 0.001423 0.45768 0.09908 0.94340 1 0.60578 0.07320 0.29259 0.03536 0.27726 0.04980 0.13412 0.02409
