/* ** ** 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 56103.386120 0.000498 20.95201 7.38155 0.97674 0 0.12936 0.04460 0.11146 0.03843 2.71037 0.19635 2.33437 0.16911 56103.387069 0.000451 11.61750 3.13148 0.98718 0 0.25491 0.06620 0.21980 0.05708 2.96142 0.21388 2.55348 0.18442 56103.388013 0.000492 16.80033 5.66014 0.98235 0 0.16443 0.05413 0.14163 0.04663 2.76252 0.19780 2.37941 0.17037 56103.389002 0.000498 12.42274 3.50617 0.98837 0 0.21880 0.05975 0.18846 0.05147 2.71807 0.19365 2.34125 0.16680 56103.390055 0.000556 10.72639 2.68267 0.96875 0 0.23285 0.05582 0.19960 0.04784 2.49769 0.17804 2.14492 0.15289 56103.391496 0.000885 16.16290 3.78782 0.98305 0 0.16299 0.03715 0.14055 0.03204 2.63436 0.14370 2.27113 0.12389 56103.922507 0.000602 11.16642 2.86698 0.99038 0 0.20095 0.04954 0.17125 0.04222 2.24389 0.16110 1.91876 0.13776 56103.923667 0.000553 12.18163 3.27461 0.97382 0 0.20763 0.05376 0.17358 0.04494 2.52921 0.18262 2.11452 0.15266 56103.924798 0.000579 10.08581 2.51923 0.99000 0 0.23890 0.05718 0.19871 0.04756 2.40952 0.17203 2.00621 0.14324 56103.926210 0.000833 26.97402 8.92031 0.97569 0 0.08872 0.02885 0.07402 0.02407 2.39311 0.14385 2.00564 0.12055
