/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 58347.965393 0.000859 0.15866 0.01771 0.96443 0 5.09955 0.20932 4.13624 0.16974 0.80908 0.08398 0.65382 0.06786 58347.966937 0.000668 0.19130 0.04768 1.00000 1 4.07723 0.41840 0.89835 0.09218 0.77999 0.17715 0.17143 0.03893 58347.968113 0.000508 0.26554 0.06732 0.97143 1 3.99078 0.46367 0.87732 0.10193 1.05969 0.23879 0.23362 0.05264 58347.969130 0.000508 0.25591 0.06363 1.00000 1 4.23648 0.49221 0.93215 0.10830 1.08414 0.23833 0.23837 0.05240 58347.970219 0.000581 0.18274 0.04488 1.00000 1 4.94476 0.48286 1.08719 0.10616 0.90362 0.20362 0.19857 0.04474 58347.971454 0.000654 0.18166 0.04489 1.00000 1 4.41448 0.42986 0.96624 0.09408 0.80193 0.18214 0.17524 0.03979 58347.972631 0.000523 0.25036 0.06366 0.97222 1 4.09294 0.46831 0.90253 0.10326 1.02471 0.23267 0.22531 0.05116 58347.974069 0.000915 0.17686 0.03757 0.95858 1 4.53711 0.37374 0.99525 0.08199 0.80244 0.15710 0.17600 0.03446
