/* ** ** 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 56097.040104 0.000498 10.32911 6.18090 0.94186 0 0.32277 0.18638 0.03828 0.02210 3.33389 0.52340 0.61600 0.08746 56097.041099 0.000498 8.98975 4.29703 0.93605 0 0.34763 0.15859 0.06553 0.02989 3.12511 0.44578 0.61750 0.08802 56097.042046 0.000448 6.41954 2.59351 0.96774 0 0.52524 0.19860 0.10388 0.03926 3.37178 0.47986 0.66403 0.09446 56097.043186 0.000686 7.68182 3.32216 0.92827 0 0.29140 0.11900 0.05751 0.02348 2.23849 0.31855 0.45275 0.06441 56097.044395 0.000524 25.20883 19.09286 0.91713 0 0.11881 0.08838 0.02329 0.01731 2.99508 0.42703 0.59890 0.08537 56097.046458 0.000596 5.80650 2.23666 0.93204 0 0.44173 0.15817 0.08849 0.03167 2.56493 0.36429 0.51975 0.07379 56097.047535 0.000480 5.94447 2.26815 0.93373 0 0.52475 0.18560 0.10902 0.03855 3.11936 0.44652 0.63899 0.09144 56097.048429 0.000414 6.40114 2.58792 0.97203 0 0.53733 0.20311 0.11130 0.04207 3.43950 0.49321 0.71119 0.10197
