/* ** ** 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 55878.181829 0.001220 0.47288 0.12858 0.98810 1 0.24987 0.03866 0.20439 0.03162 0.11816 0.02642 0.09639 0.02155 55878.184429 0.001380 0.51767 0.14238 0.96842 1 0.20450 0.03275 0.16774 0.02686 0.10586 0.02367 0.08696 0.01944 55878.187218 0.001409 0.38544 0.10211 1.00000 1 0.26414 0.03752 0.21419 0.03042 0.10181 0.02277 0.08247 0.01844 55878.189542 0.000915 0.50069 0.13881 1.00000 1 0.31168 0.05057 0.25334 0.04110 0.15606 0.03508 0.12635 0.02840 55878.191474 0.001017 0.46107 0.12480 1.00000 1 0.30775 0.04694 0.24928 0.03801 0.14189 0.03173 0.11429 0.02556 55878.194858 0.002368 0.31676 0.06448 0.98396 1 0.31144 0.03144 0.25059 0.02529 0.09865 0.01744 0.07981 0.01411 55879.264568 0.000988 0.47173 0.12913 0.98529 1 0.30805 0.04811 0.25231 0.03940 0.14532 0.03267 0.11880 0.02671 55879.267139 0.001583 0.50027 0.11346 0.96506 1 0.26893 0.03501 0.22056 0.02871 0.13454 0.02498 0.11028 0.02048
