/* ** ** 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 59467.885992 0.000367 0.20629 0.03280 0.96850 0 5.72078 0.37731 3.95626 0.25612 1.18015 0.17071 0.81019 0.11524 59467.886713 0.000353 0.25140 0.03671 0.97541 0 4.91632 0.32508 3.94593 0.26090 1.23595 0.16092 0.99325 0.12931 59467.887407 0.000341 0.21922 0.03319 0.94068 0 5.74046 0.36938 4.47421 0.28787 1.25843 0.17243 0.97878 0.13409 59467.888061 0.000312 0.22718 0.03667 0.95370 0 5.41094 0.36700 4.15695 0.28193 1.22924 0.18005 0.94262 0.13807 59467.889499 0.001126 0.24930 0.01979 0.97686 0 5.40748 0.19142 4.23025 0.14974 1.34811 0.09578 1.05291 0.07480 59467.891334 0.000709 0.25487 0.02642 0.99184 0 4.88800 0.22936 3.85757 0.18098 1.24582 0.11517 0.98277 0.09086 59467.892381 0.000339 0.24410 0.03636 1.00000 0 5.13639 0.34134 4.02687 0.26761 1.25382 0.16714 0.97996 0.13062 59467.893030 0.000310 0.24166 0.03919 0.97196 0 5.00758 0.35762 3.88857 0.27765 1.21013 0.17619 0.93848 0.13665 59467.893655 0.000315 0.22226 0.03505 0.93578 0 5.59894 0.37108 4.36923 0.28955 1.24444 0.17809 0.97197 0.13906 59467.895234 0.001264 0.24890 0.01942 0.96568 0 5.11115 0.17795 3.97209 0.13829 1.27216 0.08880 0.98951 0.06906
