/* ** ** 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 59779.963840 0.000619 0.26601 0.02145 0.98131 0 7.96692 0.29764 7.13287 0.26648 2.11925 0.15147 1.89749 0.13562 59779.965014 0.000556 0.30177 0.02466 0.98438 0 7.80094 0.30809 6.99795 0.27638 2.35411 0.16842 2.11337 0.15116 59779.966201 0.000625 0.26404 0.02131 0.97685 0 8.02345 0.29669 7.13383 0.26378 2.11849 0.15194 1.88353 0.13507 59779.967373 0.000547 0.30724 0.02563 0.99471 0 7.60653 0.30871 6.76752 0.27466 2.33703 0.17030 2.08098 0.15163 59779.968544 0.000625 0.27525 0.02228 0.98611 0 7.60649 0.28968 6.77679 0.25808 2.09367 0.14952 1.86629 0.13328 59779.969774 0.000605 0.27796 0.02241 0.97608 0 7.90291 0.30238 7.06222 0.27023 2.19668 0.15586 1.95891 0.13897 59779.970998 0.000619 0.25958 0.02089 0.98598 0 8.07105 0.29869 7.27854 0.26936 2.09510 0.14973 1.88850 0.13497 59779.972616 0.000998 0.28035 0.01782 0.99130 0 7.56960 0.22778 6.77097 0.20371 2.12217 0.11880 1.89706 0.10619
