/* ** ** 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 55698.249399 0.001148 0.54931 0.15261 0.97468 1 0.23805 0.03925 0.18923 0.03120 0.13076 0.02924 0.10390 0.02323 55698.251636 0.001089 0.43947 0.11819 1.00000 1 0.30449 0.04550 0.24271 0.03626 0.13381 0.02992 0.10667 0.02385 55698.253844 0.001118 0.42231 0.11240 0.96104 1 0.32115 0.04635 0.25600 0.03695 0.13563 0.03033 0.10811 0.02417 55698.255790 0.000828 0.69115 0.20267 0.98246 1 0.25930 0.04919 0.20667 0.03920 0.17921 0.04007 0.14286 0.03194 55698.257417 0.000799 0.52788 0.14701 0.98182 1 0.35031 0.05759 0.27925 0.04591 0.18492 0.04157 0.14741 0.03314 55698.259654 0.001438 0.39574 0.09596 0.97058 1 0.31672 0.04146 0.25248 0.03305 0.12534 0.02559 0.09991 0.02039
