/* ** ** 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 58227.933563 0.000764 0.09830 0.02308 0.99242 0 1.83103 0.13112 1.54534 0.11063 0.17999 0.04025 0.15293 0.03420 58227.934856 0.000530 0.11561 0.02736 0.99454 0 2.23687 0.17306 1.89860 0.14689 0.25861 0.05783 0.22015 0.04923 58227.935799 0.000414 0.18716 0.04640 0.98601 0 1.79197 0.17864 1.50184 0.14970 0.33538 0.07612 0.28045 0.06365 58227.936792 0.000579 0.12145 0.02880 0.98500 0 1.98158 0.15622 1.67635 0.13216 0.24066 0.05382 0.20338 0.04548 58227.937770 0.000399 0.18393 0.04379 0.97826 0 1.98345 0.18871 1.69354 0.16111 0.36482 0.07961 0.31163 0.06800 58227.938710 0.000541 0.14340 0.03480 0.97861 0 1.76724 0.15170 1.50141 0.12886 0.25342 0.05752 0.21608 0.04904 58227.939813 0.000561 0.12468 0.02960 0.97938 0 1.99297 0.15866 1.68874 0.13443 0.24849 0.05557 0.21088 0.04715 58227.941002 0.000628 0.11898 0.02857 0.97235 0 1.86822 0.14630 1.57113 0.12304 0.22229 0.05045 0.18741 0.04253 58227.942353 0.000723 0.12175 0.02927 0.98800 0 1.56521 0.12434 1.31184 0.10421 0.19057 0.04324 0.16010 0.03633 58227.943751 0.000674 0.12865 0.02792 0.97854 0 1.97370 0.14547 1.63880 0.12079 0.25391 0.05183 0.21088 0.04305
