/* ** ** 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 59020.061487 0.000515 0.19308 0.04762 0.97753 0 2.57470 0.26061 1.18545 0.11917 0.49713 0.11182 0.23027 0.05149 59020.062402 0.000399 0.23462 0.05952 0.98551 0 2.85355 0.32323 1.24529 0.14103 0.66949 0.15198 0.29079 0.06599 59020.063261 0.000460 0.18800 0.04603 0.98113 0 3.08970 0.30804 1.37270 0.13680 0.58085 0.12990 0.25684 0.05743 59020.064031 0.000310 0.30663 0.07950 0.99065 0 2.75793 0.36178 1.23309 0.16175 0.84567 0.18911 0.37799 0.08452 59020.064731 0.000391 0.21459 0.05313 0.98519 0 3.19460 0.33929 1.40803 0.14952 0.68553 0.15331 0.30125 0.06736 59020.065535 0.000414 0.24207 0.05910 0.88891 0 3.27998 0.37016 1.44824 0.16347 0.79398 0.17189 0.35024 0.07591
