/* ** ** 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 59636.646022 0.000561 0.28672 0.02349 0.96907 0 8.67822 0.33318 7.29519 0.27999 2.48826 0.18005 2.09301 0.15139 59636.647237 0.000654 0.26810 0.02186 0.97788 0 7.89779 0.29707 6.64193 0.24979 2.11738 0.15316 1.78048 0.12878 59636.648496 0.000605 0.30306 0.02501 0.98565 0 7.54587 0.29987 6.31000 0.25071 2.28684 0.16540 1.91012 0.13816 59636.649749 0.000648 0.26293 0.02116 0.98661 0 8.13092 0.29819 6.81634 0.24997 2.13786 0.15314 1.79440 0.12853 59636.650990 0.000593 0.32341 0.02708 0.98049 0 7.16659 0.29619 6.02139 0.24885 2.31773 0.16875 1.94743 0.14178 59636.652515 0.000932 0.27496 0.01765 0.98812 0 8.54052 0.25709 7.17900 0.21610 2.34833 0.13313 1.97367 0.11189
