/* ** ** 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 59109.888260 0.000475 0.25996 0.04183 0.98171 0 2.93328 0.21572 2.37330 0.17453 0.76254 0.10912 0.61568 0.08810 59109.889102 0.000367 0.30484 0.04927 0.96850 0 3.29341 0.25613 2.69118 0.20929 1.00397 0.14225 0.82218 0.11647 59109.889918 0.000448 0.27729 0.04461 0.98065 0 2.86960 0.21555 2.36446 0.17760 0.79570 0.11320 0.65556 0.09326 59109.890910 0.000544 0.20411 0.03231 0.97872 0 3.19414 0.21029 2.62479 0.17281 0.65197 0.09385 0.53589 0.07714 59109.892039 0.000584 0.18700 0.02908 0.99010 0 3.21677 0.20213 2.66524 0.16747 0.60153 0.08557 0.49823 0.07088 59109.892976 0.000353 0.29008 0.04704 0.99180 0 3.42330 0.26657 2.83826 0.22102 0.99303 0.14126 0.82352 0.11715 59109.893642 0.000312 0.36843 0.06173 0.98148 0 3.07746 0.27240 2.55062 0.22577 1.13382 0.16129 0.94005 0.13373 59109.894886 0.000932 0.21620 0.02571 0.97478 0 3.10037 0.15630 2.57546 0.12984 0.67031 0.07218 0.55668 0.05994
