/* ** ** 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 56681.848609 0.001380 0.43740 0.10147 0.96735 1 0.43494 0.05604 0.26711 0.03438 0.19024 0.03670 0.11752 0.02262 56681.980304 0.001118 0.38437 0.10177 1.00000 1 0.32794 0.04648 0.26972 0.03823 0.12605 0.02819 0.10390 0.02323 56681.982090 0.000668 0.57972 0.16428 1.00000 1 0.36104 0.06285 0.30000 0.05222 0.20930 0.04680 0.17391 0.03889 56681.983499 0.000741 0.50529 0.13923 0.98039 1 0.38263 0.06161 0.31670 0.05099 0.19334 0.04323 0.16000 0.03578 56681.985097 0.000857 0.52500 0.14238 0.98305 1 0.33478 0.05391 0.27711 0.04462 0.17576 0.03836 0.14483 0.03160 56681.987073 0.001118 0.64579 0.15307 0.98893 1 0.29574 0.04470 0.24388 0.03686 0.19098 0.03487 0.15759 0.02877
