/* ** ** 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 56721.401302 0.000709 0.27580 0.02255 0.97959 0 6.51868 0.24428 5.92062 0.22186 1.79785 0.13064 1.63371 0.11872 56721.402725 0.000715 0.27085 0.02173 0.96356 0 6.74849 0.24672 6.16565 0.22541 1.82782 0.13057 1.66996 0.11930 56721.404158 0.000718 0.27183 0.02198 0.99194 0 6.48770 0.24253 5.92753 0.22159 1.76358 0.12641 1.61129 0.11550 56721.405602 0.000726 0.23840 0.01901 0.99203 0 7.30902 0.25558 6.67756 0.23350 1.74244 0.12490 1.59188 0.11411 56721.407092 0.000764 0.24852 0.01996 0.98106 0 6.76598 0.24107 6.15346 0.21923 1.68150 0.12104 1.52987 0.11013 56721.408596 0.000741 0.25255 0.02035 0.98047 0 6.80730 0.24418 6.21907 0.22308 1.71921 0.12408 1.57065 0.11336 56721.409945 0.000608 0.30611 0.02527 1.00000 0 6.76383 0.26959 6.16452 0.24569 2.07047 0.14966 1.88617 0.13635 56721.411180 0.000628 0.32762 0.02673 0.97696 0 6.37719 0.25739 5.80570 0.23432 2.08927 0.14812 1.90312 0.13492
