/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 59770.160594 0.000909 0.18418 0.01454 0.96815 0 7.80815 0.23971 7.00395 0.21499 1.43809 0.10456 1.28867 0.09371 59770.162226 0.000723 0.23964 0.01913 0.98000 0 7.49374 0.26463 6.75695 0.23861 1.79578 0.12856 1.61921 0.11592 59770.163643 0.000694 0.24500 0.01964 0.97917 0 7.64233 0.27176 6.89074 0.24503 1.87234 0.13453 1.68821 0.12130 59770.165168 0.000830 0.20063 0.01589 0.97561 0 7.83359 0.25247 7.06315 0.22764 1.57162 0.11374 1.41705 0.10255 59770.166716 0.000718 0.23404 0.01852 0.97984 0 7.81301 0.26900 7.04563 0.24258 1.82858 0.13024 1.64902 0.11745 59770.168785 0.001351 0.23076 0.01396 0.98073 0 7.17466 0.18812 6.46263 0.16946 1.65560 0.09023 1.49172 0.08130
