/* ** ** 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 54795.875381 0.001409 0.36538 0.09584 0.98969 1 0.29039 0.03924 0.22640 0.03059 0.10610 0.02385 0.08292 0.01864 54795.877923 0.001133 0.57328 0.16174 0.98718 1 0.23093 0.03973 0.18081 0.03110 0.13239 0.02960 0.10390 0.02323 54795.880654 0.001598 0.42787 0.11425 0.99091 1 0.22266 0.03248 0.17248 0.02516 0.09527 0.02131 0.07340 0.01641 54795.885171 0.002920 0.27177 0.05608 0.99740 1 0.28518 0.02742 0.21998 0.02115 0.07750 0.01415 0.05986 0.01093 54795.941251 0.001307 0.39529 0.10467 1.00000 1 0.29423 0.04171 0.22428 0.03178 0.11631 0.02601 0.08889 0.01988 54795.943677 0.001118 0.55136 0.15178 0.90909 1 0.26656 0.04280 0.20747 0.03331 0.14697 0.03286 0.11429 0.02556 54795.946248 0.001453 0.42082 0.11303 1.00000 1 0.24479 0.03642 0.19002 0.02827 0.10301 0.02303 0.08000 0.01789 54795.949400 0.001699 0.36747 0.09703 0.98291 1 0.24235 0.03311 0.18714 0.02556 0.08905 0.02012 0.06888 0.01556 54795.952973 0.001874 0.42326 0.09786 0.99285 1 0.25634 0.03256 0.19840 0.02520 0.10850 0.02096 0.08402 0.01623
