/* ** ** 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 58344.946637 0.000463 0.16070 0.03877 0.98125 0 1.88586 0.17073 1.58815 0.14378 0.30306 0.06777 0.25520 0.05706 58344.947525 0.000425 0.20625 0.05081 0.97279 0 1.60750 0.16615 1.35848 0.14041 0.33155 0.07414 0.28019 0.06265 58344.948541 0.000590 0.13910 0.03326 0.97549 0 1.71265 0.14524 1.44747 0.12275 0.23822 0.05327 0.20134 0.04502 58344.949684 0.000553 0.15346 0.03691 0.97906 0 1.65205 0.14625 1.39622 0.12360 0.25352 0.05669 0.21426 0.04791 58344.950694 0.000457 0.19052 0.04722 0.94937 0 1.63691 0.16272 1.38341 0.13752 0.31186 0.07080 0.26356 0.05983 58344.951730 0.000579 0.14941 0.03637 0.97000 0 1.61381 0.14186 1.36396 0.11990 0.24111 0.05474 0.20378 0.04626 58344.952954 0.000645 0.12755 0.03075 0.95516 0 1.72166 0.13974 1.44971 0.11766 0.21960 0.04985 0.18560 0.04214 58344.954345 0.000747 0.12257 0.02904 0.95349 0 1.58755 0.12412 1.32974 0.10395 0.19458 0.04351 0.16287 0.03642 58344.955399 0.000307 0.27167 0.06968 0.95283 0 1.70439 0.20342 1.44081 0.17196 0.46303 0.10512 0.39142 0.08886 58344.956241 0.000535 0.15176 0.03693 0.95676 0 1.75660 0.15392 1.47880 0.12959 0.26658 0.06052 0.22335 0.05071 58344.957201 0.000425 0.24036 0.05604 0.98639 0 1.57789 0.16452 1.32149 0.13776 0.37926 0.07909 0.31777 0.06626
