/* ** ** 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 56752.319570 0.000755 0.81296 0.23778 1.00000 1 0.52364 0.10405 0.20201 0.04002 0.42570 0.09136 0.16830 0.03609 56752.321385 0.001060 0.40077 0.10674 0.95890 1 0.74238 0.10562 0.28032 0.03985 0.29752 0.06699 0.11359 0.02556 56752.323274 0.000799 0.53422 0.14900 0.98182 1 0.71513 0.11762 0.27408 0.04506 0.38204 0.08606 0.14725 0.03314 56752.324465 0.000392 1.84683 0.71535 1.00000 1 0.43203 0.13663 0.16000 0.05060 0.79789 0.17844 0.29630 0.06625 56752.325772 0.000915 0.52411 0.14886 0.98413 1 0.61934 0.10342 0.23557 0.03928 0.32460 0.07458 0.12589 0.02890 56752.327486 0.000799 0.67759 0.19742 0.92727 1 0.60143 0.11226 0.23103 0.04309 0.40753 0.09117 0.15686 0.03508 56752.329403 0.001118 0.56298 0.12758 0.97164 1 0.77708 0.10714 0.29791 0.04102 0.43748 0.07868 0.16574 0.02977
