/* ** ** 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 56135.073733 0.000744 8.91463 2.08858 0.96498 0 0.20670 0.04605 0.17747 0.03952 1.84266 0.13365 1.57991 0.11459 56135.075145 0.000668 17.66428 5.62686 0.98268 0 0.11423 0.03545 0.09855 0.03058 2.01776 0.14495 1.74069 0.12505 56135.076528 0.000715 10.21616 2.45463 0.96761 0 0.19019 0.04363 0.16407 0.03764 1.94298 0.13873 1.67612 0.11967 56135.077969 0.000726 11.04104 2.84052 0.98805 0 0.16814 0.04155 0.14504 0.03584 1.85649 0.13302 1.60137 0.11474 56135.079366 0.000671 11.82474 3.19133 0.98276 0 0.17082 0.04445 0.14667 0.03816 2.01995 0.14465 1.73791 0.12445 56135.080798 0.000761 10.59320 2.67964 0.98099 0 0.16788 0.04072 0.14431 0.03500 1.77836 0.12776 1.53154 0.11002 56135.082795 0.001236 9.09221 1.66195 0.98126 0 0.20577 0.03586 0.17693 0.03083 1.87089 0.10306 1.60878 0.08862
