/* ** ** 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 55989.305445 0.000625 6.87010 1.40200 0.96759 0 0.33135 0.06329 0.27647 0.05280 2.27643 0.16362 1.88957 0.13581 55989.306718 0.000648 8.42995 1.90445 0.95536 0 0.25962 0.05556 0.21755 0.04655 2.18857 0.15848 1.83322 0.13275 55989.307936 0.000570 8.18868 1.82785 0.97970 0 0.29738 0.06281 0.24893 0.05258 2.43519 0.17581 2.03810 0.14714 55989.309470 0.000964 8.56297 1.55276 0.96777 0 0.27593 0.04754 0.23112 0.03982 2.36277 0.13366 1.97871 0.11193 55989.633341 0.000570 21.18440 7.71330 0.97970 0 0.12843 0.04582 0.09595 0.03421 2.72066 0.19767 2.02721 0.14724 55989.634583 0.000671 11.06959 2.84376 0.96121 0 0.21412 0.05284 0.16122 0.03979 2.37027 0.16910 1.78264 0.12718 55989.635954 0.000700 10.50363 2.66902 0.97107 0 0.21432 0.05223 0.15988 0.03896 2.25112 0.16187 1.68048 0.12078 55989.637369 0.000715 10.63622 2.83196 0.95951 0 0.20341 0.05205 0.15397 0.03938 2.16354 0.15909 1.63320 0.12007 55989.638836 0.000752 8.60019 1.89475 0.96923 0 0.26179 0.05478 0.19846 0.04153 2.25142 0.15521 1.70606 0.11761
