/* ** ** 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 54937.707841 0.001656 0.40627 0.10808 0.97368 1 0.21925 0.03160 0.17670 0.02547 0.08907 0.01992 0.07207 0.01612 54937.711153 0.001656 0.46348 0.12659 0.98246 1 0.18913 0.02933 0.15338 0.02379 0.08766 0.01971 0.07106 0.01598 54937.716120 0.003312 0.33412 0.06264 0.97153 1 0.25816 0.02425 0.20531 0.01928 0.08626 0.01399 0.06862 0.01113 54937.977677 0.001743 0.36675 0.09324 0.95833 1 0.24684 0.03219 0.19967 0.02604 0.09053 0.01976 0.07304 0.01594 54937.980902 0.001482 0.38572 0.09895 0.98039 1 0.26835 0.03618 0.21782 0.02937 0.10351 0.02259 0.08400 0.01833 54937.984940 0.002556 0.33030 0.06451 0.97224 1 0.30774 0.03010 0.24778 0.02423 0.10165 0.01718 0.08182 0.01383
