/* ** ** 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 56268.093884 0.000472 10.63464 2.72799 0.98773 0 0.27020 0.06652 0.23015 0.05666 2.87352 0.20710 2.44627 0.17631 56268.094813 0.000457 16.72403 5.30059 0.99367 0 0.17977 0.05550 0.15092 0.04657 3.00652 0.21587 2.51728 0.18073 56268.095727 0.000457 9.51115 2.28563 0.99367 0 0.31250 0.07171 0.26638 0.06110 2.97220 0.21204 2.53176 0.18062 56268.096682 0.000498 16.46997 5.10429 0.97674 0 0.16885 0.05091 0.14310 0.04314 2.78097 0.19916 2.35787 0.16886 56268.097709 0.000530 10.34927 2.61565 1.00000 0 0.24630 0.05970 0.20951 0.05075 2.54901 0.18232 2.16709 0.15500 56268.098748 0.000509 12.65770 3.49870 0.96591 0 0.21884 0.05847 0.18680 0.04991 2.76998 0.19637 2.36439 0.16761 56268.099677 0.000420 14.41519 4.37434 0.97931 0 0.22851 0.06736 0.19175 0.05654 3.29395 0.23740 2.77359 0.19990 56268.100568 0.000472 13.76877 3.80890 0.98160 0 0.21267 0.05684 0.17979 0.04805 2.92823 0.20892 2.48429 0.17723 56268.101453 0.000414 14.37398 4.11626 0.96503 0 0.23827 0.06609 0.20189 0.05599 3.42485 0.24404 2.88363 0.20546 56268.102307 0.000440 10.75088 2.75588 0.99342 0 0.28825 0.07097 0.24527 0.06038 3.09891 0.22109 2.63236 0.18779 56268.103459 0.000712 9.09895 1.68940 0.98780 0 0.33432 0.05910 0.28366 0.05014 3.04199 0.17264 2.58459 0.14668
