/* ** ** 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 56053.411573 0.000946 5.73538 1.08123 0.96330 0 0.36671 0.06386 0.22533 0.03898 2.10323 0.15193 1.25405 0.09010 56053.413599 0.001079 10.34505 2.55639 0.95174 0 0.18466 0.04370 0.10830 0.02562 1.91035 0.13604 1.13112 0.08053 56053.415734 0.001056 16.39054 5.10635 0.94795 0 0.11925 0.03615 0.06974 0.02114 1.95461 0.14046 1.14169 0.08203 56053.417893 0.001102 8.06602 1.78403 0.96588 0 0.23039 0.04821 0.13292 0.02780 1.85835 0.13313 1.07622 0.07710 56053.419339 0.000344 7.26302 3.16923 0.94118 0 0.20976 0.08641 0.12035 0.04953 1.52348 0.21929 0.88061 0.12673 56053.420937 0.001253 10.77072 2.55442 0.94919 0 0.17987 0.04092 0.10340 0.02353 1.93736 0.12991 1.10724 0.07424
