/* ** ** Swift/XRT hardness ratio for PKS 1222+216. ** 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 55239.271959 0.002092 0.83969 0.25424 0.97917 1 0.08412 0.01717 0.06713 0.01370 0.07064 0.01580 0.05674 0.01269 55239.277639 0.003588 0.41096 0.10662 0.98210 1 0.10637 0.01493 0.08428 0.01183 0.04371 0.00954 0.03463 0.00756 55239.344305 0.007088 0.46939 0.09939 0.96411 1 0.08477 0.01015 0.05968 0.00714 0.03979 0.00695 0.02797 0.00488 55239.409583 0.005694 0.38719 0.08955 0.98872 1 0.08765 0.01074 0.06966 0.00854 0.03394 0.00666 0.02683 0.00526 55239.476590 0.006028 0.35330 0.07506 0.98688 1 0.10196 0.01107 0.08272 0.00898 0.03602 0.00658 0.02930 0.00535
