/* ** ** 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 57899.248087 0.000770 0.57634 0.16269 1.00000 1 0.34756 0.05983 0.26074 0.04486 0.20031 0.04481 0.15094 0.03375 57899.250208 0.001351 0.31282 0.08054 0.96774 1 0.36930 0.04632 0.28353 0.03556 0.11553 0.02598 0.08843 0.01988 57899.252503 0.000944 0.52580 0.14640 0.98112 1 0.31376 0.05204 0.23758 0.03940 0.16497 0.03689 0.12544 0.02805 57901.457512 0.000959 0.40563 0.10830 1.00000 1 0.36731 0.05358 0.29841 0.04353 0.14899 0.03332 0.12121 0.02710 57901.459386 0.000886 0.46699 0.12793 0.98361 1 0.34347 0.05251 0.28129 0.04300 0.16040 0.03646 0.13126 0.02984 57901.461376 0.001104 0.43743 0.10778 0.97805 1 0.36360 0.05016 0.29329 0.04045 0.15905 0.03247 0.12915 0.02636
