/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 55736.755245 0.000758 0.11422 0.02779 0.97328 0 1.54064 0.11955 1.33574 0.10365 0.17597 0.04057 0.15297 0.03526 55736.756738 0.000735 0.12545 0.03020 0.97244 0 1.46801 0.11766 1.27619 0.10229 0.18417 0.04181 0.16007 0.03634 55736.758213 0.000741 0.13090 0.03162 0.98047 0 1.38500 0.11445 1.20374 0.09947 0.18130 0.04115 0.15752 0.03576 55736.759591 0.000637 0.16548 0.03998 0.96364 0 1.31144 0.11991 1.13750 0.10400 0.21702 0.04853 0.18899 0.04226 55736.760930 0.000703 0.14400 0.03498 0.97942 0 1.33967 0.11605 1.15840 0.10035 0.19292 0.04379 0.16612 0.03771 55736.762548 0.000914 0.11686 0.02764 0.98418 0 1.28721 0.09906 1.10248 0.08485 0.15042 0.03364 0.12883 0.02881 55736.764434 0.000972 0.09535 0.02267 0.97619 0 1.46945 0.10349 1.26520 0.08909 0.14012 0.03182 0.12054 0.02736 55736.766147 0.000741 0.12262 0.02836 0.97656 0 1.61177 0.12333 1.37649 0.10531 0.19764 0.04313 0.16828 0.03672 55736.767800 0.000911 0.11757 0.02717 0.98095 0 1.36239 0.10370 1.16115 0.08837 0.16018 0.03496 0.13615 0.02971
