/* ** ** 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 56749.984898 0.000537 0.64328 0.18420 0.97297 1 0.42684 0.07571 0.34487 0.06117 0.27458 0.06172 0.22111 0.04970 56749.986074 0.000639 0.56015 0.15671 0.95455 1 0.41724 0.07015 0.34001 0.05717 0.23372 0.05226 0.19048 0.04259 56749.987571 0.000857 0.41540 0.11104 0.96610 1 0.41249 0.05967 0.33614 0.04862 0.17135 0.03852 0.13965 0.03139 56749.989168 0.000741 0.64608 0.18639 0.98039 1 0.30236 0.05467 0.24640 0.04456 0.19535 0.04391 0.15920 0.03579 56749.990694 0.000784 0.50450 0.13888 0.98148 1 0.36725 0.05897 0.29923 0.04804 0.18528 0.04143 0.15094 0.03375 56749.992146 0.000668 0.50170 0.13798 1.00000 1 0.42540 0.06812 0.34667 0.05551 0.21342 0.04772 0.17391 0.03889 56749.993294 0.000479 0.79544 0.24576 0.96970 1 0.38569 0.08223 0.31429 0.06701 0.30679 0.06860 0.25000 0.05590 56749.994833 0.001060 0.45328 0.10358 0.97431 1 0.42643 0.05479 0.34743 0.04464 0.19329 0.03653 0.15747 0.02976
