/* ** ** Swift/XRT hardness ratio for 3C 454.3. ** 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 54716.647914 0.000523 0.72114 0.21403 1.00000 1 0.66835 0.12928 0.30718 0.05940 0.48197 0.10849 0.22087 0.04971 54716.648872 0.000436 0.88687 0.27710 1.00000 1 0.65833 0.14366 0.30000 0.06547 0.58386 0.13056 0.26667 0.05963 54716.649831 0.000523 0.71907 0.21095 0.97222 1 0.68627 0.13031 0.31861 0.06049 0.49347 0.11035 0.22857 0.05111 54716.650790 0.000436 0.70336 0.20714 1.00000 1 0.80321 0.15392 0.38116 0.07304 0.56495 0.12634 0.26667 0.05963 54716.651995 0.000770 0.71774 0.18095 0.96453 1 0.63146 0.10282 0.29708 0.04836 0.45323 0.08724 0.21127 0.04066
