/* ** ** 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 56171.431840 0.000880 10.44846 2.62418 0.95724 0 0.20533 0.04941 0.13132 0.03158 2.14534 0.15436 1.36260 0.09749 56171.433527 0.000807 6.40418 1.26615 0.96774 0 0.40111 0.07397 0.23094 0.04258 2.56876 0.18300 1.47435 0.10502 56171.435249 0.000914 11.24766 2.84479 0.96835 0 0.20322 0.04931 0.11506 0.02791 2.28573 0.16296 1.30405 0.09293 56171.437014 0.000851 8.45414 1.90092 0.96939 0 0.29237 0.06237 0.16631 0.03546 2.47178 0.17573 1.40378 0.09974 56171.438764 0.000900 8.55081 1.97064 0.98071 0 0.27319 0.05983 0.15100 0.03307 2.33601 0.16765 1.29666 0.09305 56171.441238 0.001574 10.54001 1.96604 0.96875 0 0.23601 0.04220 0.13015 0.02327 2.48760 0.13223 1.37712 0.07319
