/* ** ** Swift/XRT hardness ratio for Cen A. ** 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 56157.786501 0.000674 9.51878 2.28783 0.98283 0 0.21268 0.04879 0.18212 0.04178 2.02443 0.14508 1.72876 0.12389 56157.787812 0.000637 11.05239 2.83407 0.98182 0 0.19750 0.04866 0.16706 0.04116 2.18282 0.15518 1.84609 0.13124 56157.789354 0.000906 7.48843 1.62084 0.98722 0 0.20358 0.04161 0.17238 0.03523 1.52450 0.10855 1.29231 0.09201 56157.790887 0.000628 10.97734 2.77638 0.98157 0 0.20229 0.04907 0.16944 0.04109 2.22063 0.15916 1.85862 0.13320 56157.792247 0.000732 8.35170 1.92063 0.97628 0 0.22730 0.04968 0.19119 0.04180 1.89837 0.13569 1.60665 0.11483 56157.793694 0.000709 8.19662 1.88799 0.98776 0 0.23443 0.05127 0.19805 0.04330 1.92155 0.13885 1.62404 0.11734 56157.795809 0.001406 8.21706 1.30904 0.96502 0 0.23348 0.03520 0.19898 0.03000 1.91851 0.09876 1.63695 0.08426
