/* ** ** 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 56764.080551 0.000483 0.33302 0.02707 0.98204 0 8.65492 0.35216 7.41047 0.30152 2.88223 0.20280 2.46752 0.17361 56764.081500 0.000466 0.30444 0.02507 0.98758 0 9.47865 0.37697 8.15288 0.32424 2.88568 0.20807 2.48104 0.17889 56764.082521 0.000556 0.26335 0.02144 0.98958 0 9.08257 0.33525 7.84284 0.28949 2.39193 0.17360 2.06540 0.14990 56764.083612 0.000535 0.29539 0.02412 0.99459 0 8.50192 0.33254 7.30752 0.28581 2.51141 0.18003 2.16043 0.15487 56764.084714 0.000567 0.25303 0.02035 0.98469 0 9.43819 0.34004 8.11367 0.29231 2.38816 0.17176 2.05435 0.14774 56764.085773 0.000492 0.30718 0.02561 1.00000 0 8.69302 0.34911 7.47755 0.30028 2.67036 0.19508 2.29627 0.16775 56764.086691 0.000425 0.33928 0.02802 0.99320 0 9.30459 0.38626 8.02589 0.33318 3.15684 0.22540 2.72313 0.19444 56764.087570 0.000454 0.33941 0.02802 0.98089 0 8.94770 0.37020 7.63213 0.31572 3.03696 0.21700 2.58798 0.18491 56764.088528 0.000503 0.31328 0.02595 0.99425 0 8.45631 0.34113 7.25801 0.29278 2.64921 0.19165 2.27431 0.16452 56764.089515 0.000483 0.33161 0.02728 0.97605 0 8.52771 0.34868 7.35598 0.30077 2.82783 0.20191 2.43912 0.17416 56764.090817 0.000819 0.29849 0.01961 0.98940 0 8.60210 0.26994 7.37805 0.23150 2.56761 0.14818 2.20265 0.12711
