/* ** ** 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 54954.638711 0.000930 0.50597 0.13864 0.96875 1 0.31808 0.04981 0.25561 0.04002 0.16094 0.03619 0.12837 0.02886 54954.640614 0.000973 0.39558 0.10473 0.98507 1 0.38836 0.05504 0.30706 0.04352 0.15363 0.03435 0.12121 0.02710 54954.642938 0.001351 0.26206 0.06628 0.97849 1 0.41853 0.04847 0.33243 0.03850 0.10968 0.02466 0.08746 0.01966 54954.645015 0.000726 0.87500 0.26755 0.98000 1 0.23560 0.04913 0.18776 0.03915 0.20615 0.04610 0.16327 0.03651 54954.646526 0.000784 0.55192 0.15489 0.98148 1 0.34497 0.05849 0.27371 0.04641 0.19039 0.04258 0.15094 0.03375 54954.648995 0.001685 0.39805 0.08001 0.98726 1 0.38520 0.04189 0.30689 0.03337 0.15333 0.02592 0.12225 0.02066 54954.714831 0.001118 0.41523 0.10595 0.97097 1 0.38803 0.05356 0.28161 0.03883 0.16112 0.03458 0.11717 0.02510
