/* ** ** 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 56029.345772 0.000773 8.92071 1.80246 0.97704 0 0.26304 0.05060 0.22957 0.04416 2.34654 0.14517 2.04790 0.12669 56029.565955 0.000501 11.02624 2.78694 0.97110 0 0.24857 0.06029 0.21692 0.05261 2.74082 0.19500 2.39182 0.17017 56029.567005 0.000550 11.91693 3.21319 0.97368 0 0.20518 0.05332 0.17905 0.04653 2.44506 0.17584 2.13372 0.15345 56029.568162 0.000608 14.03829 3.82076 0.98174 0 0.17417 0.04590 0.15199 0.04006 2.44500 0.16615 2.13367 0.14499 56029.621576 0.000608 11.51200 3.01312 0.97143 0 0.19772 0.04974 0.16738 0.04211 2.27616 0.16447 1.92691 0.13923 56029.622907 0.000723 12.12844 2.98403 0.96805 0 0.19075 0.04521 0.16148 0.03828 2.31348 0.15257 1.95851 0.12916 56029.634022 0.000582 12.36009 3.30944 0.98010 0 0.19400 0.05009 0.16511 0.04263 2.39780 0.16996 2.04076 0.14466 56029.635350 0.000747 9.05737 1.85536 0.98837 0 0.26910 0.05253 0.22903 0.04471 2.43730 0.15141 2.07438 0.12886
