/* ** ** 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 56310.756676 0.000590 13.89262 4.10857 0.97059 0 0.22343 0.06411 0.13726 0.03893 3.10401 0.22229 2.00801 0.14323 56310.757868 0.000602 8.58223 1.91441 0.93269 0 0.37376 0.07891 0.23731 0.05011 3.20766 0.23093 2.03856 0.14674 56310.758979 0.000509 15.08169 4.59123 0.98864 0 0.23504 0.06953 0.15081 0.04461 3.54483 0.25474 2.27022 0.16312 56310.760065 0.000576 12.35503 3.43250 0.97990 0 0.25728 0.06905 0.16490 0.04428 3.17867 0.22818 2.03338 0.14594 56310.761300 0.000660 10.47539 2.66052 0.98246 0 0.26952 0.06565 0.17006 0.04141 2.82328 0.20298 1.76783 0.12706 56310.762486 0.000527 13.39569 3.79331 0.95055 0 0.26855 0.07354 0.17072 0.04676 3.59743 0.25930 2.27741 0.16411 56310.763621 0.000608 14.58238 4.26939 0.93810 0 0.21702 0.06162 0.13437 0.03811 3.16469 0.22579 2.01820 0.14396 56310.764902 0.000674 9.53596 2.29400 0.96137 0 0.29632 0.06800 0.18388 0.04219 2.82571 0.20393 1.75660 0.12677 56310.766138 0.000561 10.19211 2.51123 0.98969 0 0.31940 0.07531 0.20145 0.04748 3.25538 0.23292 2.06541 0.14775 56310.767376 0.000677 18.76822 5.48008 0.96154 0 0.19173 0.05466 0.12048 0.03431 3.59847 0.22695 2.25675 0.14229
