/* ** ** 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 55705.340061 0.000915 0.61518 0.17536 1.00000 1 0.25329 0.04478 0.20645 0.03650 0.15582 0.03484 0.12699 0.02839 55705.341877 0.000901 0.55178 0.15537 1.00000 1 0.28427 0.04820 0.23266 0.03945 0.15685 0.03526 0.12838 0.02886 55705.343867 0.001089 0.48274 0.13328 0.98667 1 0.27083 0.04294 0.22166 0.03514 0.13074 0.02955 0.10701 0.02419 55705.345842 0.000886 0.61172 0.17399 0.96721 1 0.27082 0.04761 0.22166 0.03896 0.16567 0.03704 0.13559 0.03032 55705.347861 0.001133 0.42791 0.11215 0.96154 1 0.31670 0.04488 0.25921 0.03674 0.13552 0.02988 0.11092 0.02445 55705.349866 0.000872 0.53704 0.14977 1.00000 1 0.30333 0.05056 0.24828 0.04138 0.16290 0.03643 0.13333 0.02981 55705.352015 0.001278 0.42645 0.11393 0.97727 1 0.26652 0.03896 0.21813 0.03189 0.11366 0.02541 0.09302 0.02080 55705.354761 0.001467 0.41250 0.09303 0.99794 1 0.32913 0.04051 0.26939 0.03316 0.13576 0.02566 0.11112 0.02100
