/* ** ** 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 54157.309531 0.034205 0.49476 0.12295 0.03521 1 0.38783 0.05546 0.25461 0.03513 0.19189 0.03900 0.12544 0.02460 54157.443533 0.034235 0.65254 0.13859 0.03942 1 0.29293 0.03922 0.24330 0.03257 0.19115 0.03152 0.15887 0.02619 54157.577126 0.033956 0.47534 0.10463 0.03333 1 0.40438 0.05145 0.33496 0.04261 0.19222 0.03453 0.15914 0.02858 54157.673611 0.001743 0.46564 0.12707 0.96667 1 0.23654 0.03661 0.14574 0.02254 0.11014 0.02476 0.06862 0.01542 54157.676908 0.001554 0.89748 0.23296 0.95099 1 0.19817 0.03526 0.12260 0.02181 0.17785 0.03361 0.11006 0.02080 54157.740290 0.001002 0.56976 0.16169 0.98551 1 0.38466 0.06641 0.20606 0.03534 0.21916 0.04936 0.11764 0.02631 54157.742265 0.000973 0.70347 0.20856 0.98507 1 0.33813 0.06535 0.17080 0.03300 0.23787 0.05347 0.12061 0.02711 54157.744183 0.000944 0.91492 0.24729 0.98129 1 0.35923 0.06789 0.18426 0.03482 0.32866 0.06351 0.16870 0.03259 54157.809882 0.002615 0.56779 0.12573 0.96865 1 0.30623 0.04071 0.13103 0.01736 0.17387 0.03079 0.07341 0.01298
