/* ** ** 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 56055.072940 0.000648 8.92845 2.13809 0.97768 0 0.23527 0.05374 0.20115 0.04597 2.10059 0.15102 1.80304 0.12961 56055.074193 0.000605 8.23701 1.83559 0.98086 0 0.27677 0.05847 0.23724 0.05012 2.27978 0.16176 1.95396 0.13864 56055.075408 0.000611 10.83097 2.83245 0.98104 0 0.20592 0.05176 0.17554 0.04411 2.23028 0.16107 1.89992 0.13720 56055.076684 0.000666 7.44772 1.63526 0.96522 0 0.27864 0.05778 0.23775 0.04931 2.07523 0.14986 1.77155 0.12793 56055.077983 0.000634 11.06634 2.85450 0.95434 0 0.20124 0.04987 0.17068 0.04232 2.22696 0.15937 1.89688 0.13574 56055.079230 0.000613 11.88682 3.15754 0.96698 0 0.19194 0.04911 0.16401 0.04197 2.28157 0.16268 1.95087 0.13911 56055.080425 0.000582 7.21611 1.56958 0.99005 0 0.32453 0.06670 0.27765 0.05705 2.34186 0.16684 2.00015 0.14249 56055.081591 0.000584 11.54840 3.12260 0.97525 0 0.20549 0.05356 0.17458 0.04550 2.37311 0.17062 2.00440 0.14409 56055.083102 0.000926 7.18154 1.31443 0.96875 0 0.28070 0.04838 0.23894 0.04118 2.01584 0.12421 1.71525 0.10568
