/* ** ** 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 57857.268564 0.001118 0.29906 0.07677 0.98701 1 0.43245 0.05358 0.34981 0.04334 0.12933 0.02908 0.10472 0.02354 57857.270612 0.000930 0.48286 0.12877 1.00000 1 0.34029 0.05216 0.27171 0.04165 0.16431 0.03586 0.13125 0.02864 57857.272472 0.000930 0.51671 0.14275 0.98438 1 0.30461 0.04942 0.24516 0.03977 0.15740 0.03520 0.12699 0.02839 57857.274578 0.001177 0.39104 0.10128 0.98765 1 0.33363 0.04592 0.26784 0.03687 0.13046 0.02862 0.10449 0.02292 57857.276495 0.000741 0.48188 0.13221 0.98039 1 0.41333 0.06571 0.33162 0.05272 0.19918 0.04454 0.16000 0.03578 57857.278529 0.001293 0.36398 0.08436 0.97664 1 0.40645 0.04854 0.32455 0.03875 0.14794 0.02939 0.11823 0.02348
