/* ** ** 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 56071.651349 0.000680 7.17833 1.51848 0.98723 0 0.28332 0.05636 0.23763 0.04728 2.03375 0.14625 1.70627 0.12269 56071.652662 0.000634 7.51612 1.64786 0.97717 0 0.29958 0.06211 0.24877 0.05158 2.25164 0.16047 1.86449 0.13288 56071.653938 0.000642 7.56551 1.63607 0.96847 0 0.29730 0.06069 0.24531 0.05007 2.24922 0.16054 1.85338 0.13228 56071.655263 0.000683 11.05842 2.84234 0.97034 0 0.18911 0.04669 0.15669 0.03868 2.09129 0.14944 1.73361 0.12387 56071.656597 0.000651 10.95809 2.81613 0.97333 0 0.20062 0.04953 0.16683 0.04118 2.19846 0.15675 1.82628 0.13021 56071.657905 0.000657 10.69671 2.67478 0.96035 0 0.20377 0.04882 0.17003 0.04074 2.17963 0.15596 1.81868 0.13014 56071.659210 0.000648 9.83131 2.43131 0.99107 0 0.21782 0.05156 0.18234 0.04317 2.14145 0.15331 1.79022 0.12816 56071.660475 0.000616 13.56364 3.88489 0.99061 0 0.16840 0.04671 0.13853 0.03842 2.28410 0.16321 1.88150 0.13443 56071.661777 0.000686 9.03098 2.10586 0.98312 0 0.23241 0.05162 0.19144 0.04252 2.09892 0.14917 1.73559 0.12335
