/* ** ** 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 59675.119728 0.000396 0.29803 0.02448 0.99270 0 10.79406 0.42814 9.77650 0.38771 3.21700 0.23141 2.92103 0.21010 59675.120590 0.000466 0.25829 0.02112 0.98758 0 10.63308 0.39476 9.57688 0.35548 2.74644 0.20014 2.47580 0.18042 59675.121499 0.000443 0.28877 0.02383 0.98693 0 9.93874 0.39020 9.02024 0.35411 2.86997 0.20835 2.60565 0.18914 59675.122367 0.000425 0.29133 0.02418 0.99320 0 10.12695 0.39864 9.21528 0.36277 2.95033 0.21554 2.68253 0.19601 59675.123174 0.000382 0.30934 0.02569 0.99242 0 10.75246 0.43386 9.69854 0.39130 3.32613 0.24146 3.00346 0.21802 59675.124036 0.000480 0.28858 0.02344 0.98795 0 9.34859 0.36087 8.43096 0.32541 2.69782 0.19279 2.43331 0.17388 59675.125000 0.000483 0.24118 0.01964 1.00000 0 10.82629 0.38910 9.73904 0.35002 2.61103 0.19076 2.34520 0.17136 59675.125931 0.000448 0.26940 0.02240 0.98710 0 10.39118 0.39360 9.41302 0.35649 2.79937 0.20726 2.53622 0.18778 59675.126938 0.000558 0.22813 0.01838 0.97927 0 9.99099 0.34953 9.12550 0.31925 2.27920 0.16545 2.08176 0.15111 59675.127968 0.000472 0.25569 0.02103 0.99387 0 10.49136 0.39060 9.45639 0.35214 2.68257 0.19672 2.41882 0.17743 59675.129146 0.000706 0.31767 0.02048 0.99590 0 9.42425 0.30036 8.51577 0.27141 2.99377 0.16778 2.70902 0.15176
