/* ** ** 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 56870.917581 0.000816 0.35911 0.03014 0.94326 0 12.83285 0.54867 4.11359 0.17543 4.60846 0.33285 1.48087 0.10674 56870.919210 0.000813 0.42137 0.03599 0.93950 0 11.68797 0.53758 3.54809 0.16318 4.92492 0.35445 1.49406 0.10753 56870.920934 0.000911 0.34177 0.02857 0.95556 0 12.55223 0.52411 3.81873 0.15943 4.28997 0.31063 1.30349 0.09438 56870.922673 0.000828 0.42824 0.03666 0.95105 0 11.19382 0.52080 3.39238 0.15782 4.79369 0.34453 1.45202 0.10435 56870.924291 0.000790 0.43713 0.03772 0.96703 0 11.29006 0.53364 3.40506 0.16094 4.93518 0.35630 1.49012 0.10757 56870.926762 0.001681 0.39476 0.02463 0.96386 0 11.05379 0.36688 3.31549 0.11002 4.36358 0.23055 1.30679 0.06904
