/* ** ** 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 56025.266604 0.000524 17.07089 5.28789 0.98895 0 0.15952 0.04810 0.13039 0.03932 2.72309 0.19310 2.23897 0.15876 56025.267947 0.000819 10.80114 2.18886 0.99041 0 0.24687 0.04798 0.20442 0.03973 2.66643 0.15304 2.20297 0.12643 56025.739744 0.000666 8.12073 1.81529 0.96957 0 0.26888 0.05693 0.21947 0.04649 2.18350 0.15645 1.77583 0.12724 56025.741084 0.000674 13.07668 3.70498 0.98283 0 0.16395 0.04493 0.13193 0.03616 2.14390 0.15407 1.72478 0.12394 56025.742377 0.000619 9.13208 2.14361 0.98598 0 0.25823 0.05775 0.20653 0.04618 2.35814 0.16829 1.88877 0.13479 56025.743595 0.000599 10.48151 2.61988 0.97585 0 0.23347 0.05593 0.18806 0.04505 2.44717 0.17464 1.97292 0.14079 56025.745352 0.001157 8.87671 1.61880 0.96500 0 0.23818 0.04137 0.19103 0.03317 2.11425 0.11756 1.70046 0.09455
