/* ** ** 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 56017.448288 0.000619 7.80081 1.68870 0.97664 0 0.34686 0.07080 0.24161 0.04932 2.70579 0.19504 1.88474 0.13585 56017.449515 0.000608 8.44255 1.95135 0.98095 0 0.32559 0.07151 0.22679 0.04981 2.74882 0.19784 1.91471 0.13781 56017.450742 0.000619 10.51976 2.56508 0.96262 0 0.26164 0.06096 0.18225 0.04246 2.75244 0.19781 1.91723 0.13779 56017.451934 0.000573 13.26299 3.66951 0.97980 0 0.22123 0.05913 0.15410 0.04119 2.93423 0.20994 2.04386 0.14623 56017.453048 0.000541 9.21959 2.14459 0.98396 0 0.33512 0.07416 0.23343 0.05166 3.08965 0.22139 2.15212 0.15421 56017.454231 0.000642 8.47368 1.82433 0.96249 0 0.34569 0.07056 0.24079 0.04915 2.92927 0.20049 2.04040 0.13966 56017.933182 0.001059 10.26274 2.52130 0.95902 0 0.29702 0.06980 0.10986 0.02582 3.04824 0.21850 1.12748 0.08082 56017.934554 0.000312 8.49513 3.99598 0.95370 0 0.30428 0.13608 0.11255 0.05033 2.58491 0.37691 0.95610 0.13941 56017.935980 0.001114 7.34426 1.58555 0.95844 0 0.39521 0.08049 0.14618 0.02977 2.90255 0.20782 1.07359 0.07687 56017.937407 0.000312 12.13015 6.30888 0.95370 0 0.21665 0.10832 0.08013 0.04007 2.62797 0.37630 0.97203 0.13918 56017.938176 0.000457 9.87082 3.90383 0.96835 0 0.26889 0.10163 0.09946 0.03759 2.65416 0.30904 0.98172 0.11431 56017.939455 0.000822 12.00851 3.83163 0.94366 0 0.23963 0.07376 0.08863 0.02728 2.87757 0.24178 1.06435 0.08943
