/* ** ** 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 58144.235032 0.000421 0.94809 0.29360 0.96552 1 0.37224 0.07974 0.30207 0.06471 0.35292 0.07892 0.28572 0.06389 58144.236789 0.001336 0.22233 0.05537 0.97826 1 0.49259 0.05283 0.39772 0.04265 0.10952 0.02462 0.08844 0.01988 58144.267317 0.029191 0.27905 0.07086 0.03974 1 0.47093 0.05657 0.35804 0.04299 0.13142 0.02940 0.10017 0.02240 58144.297161 0.000654 0.87983 0.26672 1.00000 1 0.27241 0.05733 0.21209 0.04463 0.23968 0.05230 0.18667 0.04073 58144.298555 0.000741 0.61750 0.17138 0.96078 1 0.35681 0.06119 0.27755 0.04760 0.22033 0.04808 0.17143 0.03741 58144.299993 0.000697 0.55040 0.15511 0.97917 1 0.39780 0.06822 0.30909 0.05301 0.21895 0.04896 0.17021 0.03806 58144.301388 0.000697 0.56464 0.15801 0.95833 1 0.39246 0.06541 0.30638 0.05106 0.22160 0.04981 0.17304 0.03890 58144.303450 0.001365 0.54305 0.11688 0.97821 1 0.34991 0.04525 0.27227 0.03521 0.19002 0.03269 0.14747 0.02537
