/* ** ** 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 58671.954617 0.000802 0.15822 0.04034 0.95668 0 2.41339 0.22813 0.97993 0.08690 0.38185 0.09042 0.15120 0.03381 58671.956550 0.001131 0.17666 0.04367 0.96675 0 1.90081 0.18656 0.60706 0.05844 0.33579 0.07619 0.10600 0.02370 58671.958526 0.000845 0.15826 0.03826 0.96918 0 2.40806 0.22055 0.90396 0.08268 0.38109 0.08527 0.14158 0.03166 58671.960352 0.000981 0.20072 0.04902 0.96755 0 2.20727 0.22385 0.64819 0.06462 0.44305 0.09844 0.12826 0.02799 58671.962577 0.001244 0.15429 0.03836 0.95116 0 2.12798 0.19886 0.59794 0.05503 0.32833 0.07565 0.09669 0.02194 58671.965239 0.001418 0.23278 0.04826 0.96327 0 1.86489 0.16574 0.58248 0.05050 0.43411 0.08132 0.12910 0.02367
