/* ** ** 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 56131.535160 0.000310 11.57543 6.27587 0.96262 0 0.14317 0.07447 0.08347 0.04174 1.65722 0.25342 0.97168 0.13927 56131.536462 0.000992 9.54165 2.27285 0.95918 0 0.17849 0.04053 0.12675 0.02876 1.70307 0.12269 1.19880 0.08629 56131.538432 0.000978 8.23668 1.90188 0.96154 0 0.21833 0.04793 0.14861 0.03265 1.79829 0.12866 1.21998 0.08729 56131.539899 0.000489 6.90806 2.29188 0.91716 0 0.20423 0.06329 0.13971 0.04328 1.41084 0.16719 0.96155 0.11391 56131.541386 0.000998 7.12911 1.51574 0.97391 0 0.24488 0.04898 0.16421 0.03284 1.74579 0.12586 1.17228 0.08451 56131.543403 0.001019 12.40963 3.53705 0.94602 0 0.14119 0.03894 0.09622 0.02650 1.75216 0.12594 1.18597 0.08524 56131.545701 0.001279 8.42344 1.65568 0.95249 0 0.22759 0.04249 0.15310 0.02858 1.91709 0.11790 1.28857 0.07925
