/* ** ** 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 56117.831935 0.000657 8.74503 1.99108 0.96035 0 0.24088 0.05206 0.20935 0.04525 2.10654 0.15083 1.82287 0.13051 56117.833254 0.000663 9.93932 2.42449 0.97380 0 0.20439 0.04764 0.17789 0.04146 2.03149 0.14626 1.76828 0.12731 56117.834531 0.000613 7.50413 1.63242 0.96226 0 0.29871 0.06138 0.26028 0.05349 2.24154 0.16000 1.95315 0.13942 56117.835786 0.000642 7.65617 1.70798 0.97748 0 0.27382 0.05785 0.23847 0.05038 2.09640 0.15025 1.82448 0.13076 56117.837149 0.000720 6.66893 1.36086 0.95582 0 0.28634 0.05470 0.24917 0.04760 1.90960 0.13707 1.66127 0.11925 56117.838558 0.000689 8.17615 1.84597 0.96639 0 0.24179 0.05176 0.21037 0.04503 1.97694 0.14191 1.71906 0.12339 56117.839805 0.000558 9.25045 2.20175 0.97927 0 0.26127 0.05931 0.22723 0.05158 2.41688 0.17304 2.10257 0.15054 56117.841055 0.000692 6.64912 1.37990 0.96653 0 0.29462 0.05733 0.25628 0.04987 1.95897 0.14126 1.70475 0.12292 56117.842381 0.000634 7.47520 1.57283 0.96804 0 0.30049 0.05961 0.26172 0.05192 2.24622 0.15746 1.95702 0.13719
