/* ** ** 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 56179.234244 0.000350 4.55191 2.51008 0.94215 0 0.26165 0.13162 0.06968 0.03484 1.19102 0.26906 0.34952 0.07861 56179.234993 0.000399 11.85797 8.74114 0.87681 0 0.13519 0.09567 0.03257 0.02303 1.60309 0.33100 0.39369 0.08115 56179.236075 0.000683 9.84514 4.62341 0.96186 0 0.19306 0.08635 0.04512 0.02018 1.90074 0.27209 0.43638 0.06244 56179.237317 0.000558 5.73156 2.22542 0.91710 0 0.42967 0.15521 0.09654 0.03488 2.46267 0.35054 0.56341 0.08005 56179.238474 0.000599 24.11898 17.41753 0.91304 0 0.09322 0.06597 0.02131 0.01507 2.24831 0.32324 0.52412 0.07500 56179.239374 0.000301 18.52686 18.98592 0.97115 0 0.10011 0.10011 0.02131 0.02131 1.85467 0.41542 0.39670 0.08870 56179.240256 0.000582 5.97856 2.31399 0.95025 0 0.37045 0.13313 0.08590 0.03082 2.21478 0.31832 0.51747 0.07422
