/* ** ** 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 56121.512640 0.000677 10.51866 2.64263 0.96581 0 0.19603 0.04722 0.16794 0.04047 2.06199 0.14700 1.76501 0.12583 56121.514087 0.000770 9.68382 2.37166 0.98120 0 0.18533 0.04343 0.15757 0.03692 1.79466 0.12776 1.53039 0.10894 56121.515569 0.000712 8.66898 1.94917 0.97967 0 0.22460 0.04789 0.18997 0.04050 1.94706 0.13897 1.64908 0.11769 56121.516984 0.000703 11.09100 2.80309 0.97119 0 0.17897 0.04341 0.15272 0.03704 1.98501 0.14102 1.69088 0.12011 56121.518459 0.000773 9.55194 2.31358 0.96255 0 0.19219 0.04451 0.16290 0.03773 1.83578 0.13028 1.55841 0.11059 56121.519958 0.000726 10.49168 2.62483 0.96414 0 0.18207 0.04365 0.15579 0.03735 1.91024 0.13654 1.64004 0.11722 56121.522131 0.001447 7.77380 1.27174 0.96800 0 0.22861 0.03540 0.19497 0.03020 1.77718 0.09368 1.51061 0.07963
