/* ** ** 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 54118.219642 0.001206 0.35390 0.09273 1.00000 1 0.34116 0.04593 0.27125 0.03652 0.12074 0.02714 0.09591 0.02156 54118.221661 0.000813 0.41977 0.11244 0.98214 1 0.44505 0.06562 0.34717 0.05119 0.18682 0.04178 0.14546 0.03252 54118.223143 0.000668 0.65693 0.19018 1.00000 1 0.33960 0.06244 0.26492 0.04870 0.22309 0.04989 0.17392 0.03889 54118.224682 0.000872 0.54652 0.15259 0.98333 1 0.31713 0.05301 0.24760 0.04139 0.17332 0.03876 0.13559 0.03032 54118.226483 0.000930 0.38414 0.09946 1.00000 1 0.43826 0.06032 0.34130 0.04697 0.16835 0.03692 0.13064 0.02865 54118.228720 0.001307 0.39422 0.09945 1.00000 1 0.31752 0.04282 0.24719 0.03333 0.12517 0.02669 0.09778 0.02085 54118.230783 0.000755 0.56381 0.15839 0.98077 1 0.35868 0.06099 0.27843 0.04734 0.20223 0.04522 0.15686 0.03508 54118.232206 0.000668 0.70819 0.20893 0.97826 1 0.32482 0.06251 0.25117 0.04834 0.23004 0.05144 0.17778 0.03975 54118.234821 0.001946 0.56397 0.11461 0.97408 1 0.26577 0.03238 0.20673 0.02518 0.14989 0.02438 0.11615 0.01889
