/* ** ** 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 55335.925649 0.001293 0.69861 0.20368 1.00000 1 0.15715 0.02940 0.12943 0.02421 0.10978 0.02455 0.08989 0.02010 55335.928336 0.001394 0.55973 0.15627 0.98958 1 0.18269 0.03054 0.15115 0.02527 0.10226 0.02287 0.08421 0.01883 55335.930500 0.000770 1.23319 0.41517 1.00000 1 0.14768 0.03717 0.12230 0.03078 0.18211 0.04072 0.15094 0.03375 55335.933144 0.001874 0.36547 0.09567 0.99225 1 0.20808 0.02832 0.17143 0.02333 0.07605 0.01701 0.06250 0.01398 55335.936601 0.001583 0.50930 0.13691 0.95725 1 0.19208 0.03016 0.15844 0.02487 0.09783 0.02135 0.08051 0.01757
