/* ** ** 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 57721.053535 0.000978 0.15244 0.03667 0.96746 0 1.07841 0.09553 0.80946 0.07171 0.16440 0.03676 0.12253 0.02740 57721.055283 0.000770 0.20720 0.05107 0.97744 0 0.98496 0.10211 0.74367 0.07710 0.20408 0.04563 0.15410 0.03446 57721.056799 0.000747 0.18326 0.04573 0.96124 0 1.14092 0.11279 0.86148 0.08516 0.20909 0.04790 0.15789 0.03617 57721.058749 0.001204 0.11710 0.02773 0.97356 0 1.11884 0.08722 0.84487 0.06586 0.13102 0.02930 0.09893 0.02212 57721.060885 0.000932 0.13748 0.03282 0.97516 0 1.22923 0.10285 0.92745 0.07760 0.16900 0.03779 0.12760 0.02853 57721.062800 0.000984 0.16289 0.03936 0.96765 0 0.99161 0.09089 0.74841 0.06859 0.16152 0.03612 0.12178 0.02723
