/* ** ** 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 58921.076094 0.000726 0.24538 0.06129 0.98000 1 2.65508 0.29555 0.66451 0.07396 0.65149 0.14569 0.16327 0.03651 58921.077779 0.000959 0.19349 0.04636 1.00000 1 2.62702 0.25995 0.65813 0.06512 0.50830 0.11093 0.12727 0.02777 58921.079478 0.000741 0.25666 0.06513 1.00000 1 2.42527 0.28249 0.60737 0.07074 0.62247 0.14033 0.15569 0.03510 58921.080902 0.000683 0.31401 0.08081 0.97872 1 2.21605 0.28220 0.54979 0.07000 0.69586 0.15561 0.17391 0.03889 58921.082194 0.000610 0.34048 0.08674 0.97619 1 2.37750 0.30591 0.59759 0.07689 0.80949 0.17800 0.20342 0.04473 58921.083502 0.000697 0.29038 0.07437 0.97917 1 2.34670 0.28522 0.58215 0.07074 0.68144 0.15361 0.16894 0.03808 58921.085012 0.000813 0.27846 0.07060 0.98214 1 2.08205 0.24881 0.52261 0.06245 0.57978 0.12965 0.14546 0.03252 58921.086988 0.001162 0.26669 0.05335 0.98601 1 2.41422 0.22601 0.60871 0.05698 0.64386 0.11383 0.16227 0.02869
