/* ** ** 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 54936.643948 0.001409 0.44114 0.11935 1.00000 1 0.23001 0.03462 0.18580 0.02796 0.10146 0.02281 0.08205 0.01845 54936.646969 0.001612 0.49866 0.12002 0.98898 1 0.23429 0.03269 0.19009 0.02653 0.11683 0.02291 0.09474 0.01858 54936.705391 0.001177 0.47968 0.13137 0.98765 1 0.26017 0.04114 0.20779 0.03286 0.12480 0.02791 0.10000 0.02236 54936.708209 0.001641 0.53852 0.15086 0.99115 1 0.16401 0.02742 0.13174 0.02202 0.08833 0.01986 0.07107 0.01598 54936.712566 0.002716 0.44173 0.09607 0.97902 1 0.18887 0.02264 0.15174 0.01819 0.08343 0.01514 0.06707 0.01217
