/* ** ** 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 56015.450626 0.000619 0.36739 0.03107 0.98131 0 6.87987 0.29905 5.17728 0.22347 2.52759 0.18334 1.88778 0.13579 56015.451867 0.000622 0.38305 0.03234 1.00000 0 7.10965 0.31735 4.81793 0.21499 2.72335 0.19513 1.84423 0.13213 56015.453134 0.000645 0.34960 0.02948 0.95516 0 7.71542 0.32466 5.24549 0.22072 2.69734 0.19707 1.83227 0.13390 56015.454399 0.000619 0.34917 0.02930 0.97664 0 7.91075 0.33678 5.39606 0.22967 2.76218 0.19978 1.88226 0.13619 56015.455660 0.000642 0.35171 0.02939 0.98198 0 7.65299 0.32930 5.18037 0.22287 2.69167 0.19285 1.81885 0.13031 56015.456948 0.000645 0.34115 0.02862 0.97758 0 7.86834 0.33043 5.28053 0.22172 2.68426 0.19492 1.79978 0.13066 56015.458215 0.000622 0.34365 0.02866 0.99070 0 8.08479 0.34197 5.40693 0.22867 2.77834 0.19973 1.85667 0.13346 56015.459419 0.000582 0.38838 0.03261 0.98507 0 7.67567 0.34117 5.19715 0.23099 2.98104 0.21236 2.01794 0.14373 56015.460900 0.000900 0.33999 0.02341 0.99678 0 8.25641 0.28659 5.53723 0.19219 2.80712 0.16693 1.88245 0.11192
