/* ** ** 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 59660.066941 0.000550 0.28927 0.02353 0.99474 0 8.17115 0.31460 7.25416 0.27932 2.36369 0.16940 2.09748 0.15032 59660.068012 0.000521 0.33333 0.02751 0.98889 0 7.63388 0.31729 6.74418 0.28030 2.54463 0.18144 2.24961 0.16040 59660.069030 0.000498 0.34210 0.02829 0.99419 0 7.76178 0.32494 6.84806 0.28664 2.65529 0.18936 2.34170 0.16697 59660.070191 0.000663 0.29518 0.02169 0.99003 0 8.13525 0.28760 7.28629 0.25757 2.40137 0.15470 2.15085 0.13855 59660.264107 0.000683 0.27085 0.02193 0.97881 0 7.59967 0.28352 6.31843 0.23570 2.05840 0.14790 1.71128 0.12296 59660.265409 0.000619 0.29160 0.02406 0.99533 0 7.50947 0.29566 6.31469 0.24862 2.18974 0.15880 1.84151 0.13354 59660.266589 0.000561 0.32997 0.02717 0.94330 0 7.82119 0.31926 6.57275 0.26830 2.58074 0.18458 2.16851 0.15510 59660.267946 0.000796 0.31484 0.02190 0.99636 0 7.63015 0.26131 6.41684 0.21976 2.40225 0.14548 2.02032 0.12235
