/* ** ** 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 56073.656216 0.000686 11.20289 2.83250 0.97046 0 0.18168 0.04407 0.15410 0.03738 2.03534 0.14529 1.73241 0.12366 56073.657593 0.000692 7.97019 1.80316 0.97908 0 0.25099 0.05388 0.21283 0.04570 2.00046 0.14297 1.69649 0.12122 56073.659002 0.000718 8.75924 2.04478 0.96774 0 0.22419 0.04983 0.18970 0.04215 1.96377 0.14019 1.66022 0.11851 56073.660461 0.000741 8.25727 1.86762 0.97266 0 0.22899 0.04915 0.19316 0.04147 1.89080 0.13490 1.59640 0.11390 56073.661896 0.000694 9.18408 2.19322 0.97500 0 0.21823 0.04973 0.18573 0.04232 2.00428 0.14330 1.70054 0.12156 56073.663360 0.000770 11.43144 2.98684 0.97368 0 0.15704 0.03946 0.13361 0.03358 1.79516 0.12866 1.52866 0.10956 56073.665383 0.001253 10.52790 2.00822 0.97691 0 0.18724 0.03428 0.15857 0.02904 1.97126 0.10548 1.67456 0.08960
