/* ** ** 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 55737.619030 0.001597 0.43660 0.11714 0.96196 0 0.22984 0.03407 0.17304 0.02564 0.10035 0.02244 0.07546 0.01687 55737.622543 0.001916 0.41087 0.11039 0.97281 0 0.19838 0.02915 0.15031 0.02209 0.08151 0.01833 0.06187 0.01392 55737.625572 0.001114 0.78908 0.23899 0.96883 0 0.17834 0.03618 0.13539 0.02746 0.14073 0.03165 0.10682 0.02403 55737.627901 0.001215 0.73250 0.21757 0.95714 0 0.17726 0.03411 0.13455 0.02589 0.12984 0.02938 0.09857 0.02230 55737.630699 0.001583 0.46113 0.12647 0.96527 0 0.21599 0.03390 0.16269 0.02553 0.09960 0.02240 0.07546 0.01697 55737.634198 0.001916 0.61111 0.16580 0.96677 0 0.15108 0.02535 0.11270 0.01891 0.09232 0.01968 0.06886 0.01468
