/* ** ** Swift/XRT hardness ratio for OJ 287. ** 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 54781.140861 0.001380 0.47169 0.12877 0.98947 1 0.22069 0.03456 0.17978 0.02815 0.10410 0.02328 0.08511 0.01903 54781.143882 0.001641 0.52678 0.14617 0.97345 1 0.16876 0.02746 0.13782 0.02242 0.08890 0.01998 0.07236 0.01627 54781.148080 0.002556 0.42491 0.08592 0.96924 1 0.23549 0.02595 0.19279 0.02124 0.10006 0.01697 0.08184 0.01387 54781.211736 0.001656 0.40730 0.10783 0.96491 1 0.21665 0.03070 0.17821 0.02526 0.08824 0.01973 0.07273 0.01626 54781.248695 0.035303 0.49628 0.09284 0.08733 1 0.19722 0.02137 0.16326 0.01769 0.09788 0.01493 0.08103 0.01236
