/* ** ** 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 57557.816834 0.000581 0.68107 0.19700 1.00000 1 0.62216 0.11608 0.30394 0.05670 0.42373 0.09366 0.20749 0.04586 57557.817953 0.000537 0.61872 0.17379 1.00000 1 0.76506 0.13526 0.36572 0.06465 0.47335 0.10332 0.22703 0.04954 57557.819202 0.000712 0.39234 0.10428 1.00000 1 0.85820 0.12328 0.41489 0.05959 0.33670 0.07530 0.16327 0.03651 57557.820597 0.000683 0.57240 0.16297 0.97872 1 0.62757 0.11059 0.30348 0.05348 0.35922 0.08033 0.17391 0.03889 57557.822441 0.001162 0.57239 0.11637 0.94576 1 0.72193 0.08791 0.35195 0.04285 0.41323 0.06728 0.20023 0.03260
