/* ** ** 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 58617.106731 0.000463 0.13776 0.03342 0.97500 0 2.24341 0.19274 1.84740 0.15869 0.30906 0.07012 0.25356 0.05752 58617.107640 0.000446 0.14413 0.03456 0.97403 0 2.25743 0.19561 1.85356 0.16061 0.32537 0.07276 0.26711 0.05973 58617.108528 0.000443 0.18617 0.04493 0.98693 0 1.81121 0.17463 1.48176 0.14286 0.33720 0.07460 0.27522 0.06089 58617.109341 0.000370 0.15714 0.03738 0.94531 0 2.66244 0.23288 2.18510 0.19113 0.41837 0.09255 0.34346 0.07599 58617.110120 0.000402 0.18140 0.04468 0.97842 0 1.95336 0.18746 1.60365 0.15390 0.35434 0.08039 0.29085 0.06598 58617.110829 0.000307 0.23294 0.05796 0.99057 0 2.00483 0.21876 1.63379 0.17826 0.46701 0.10443 0.38159 0.08533 58617.111564 0.000428 0.15291 0.03727 0.97297 0 2.26637 0.19834 1.85578 0.16241 0.34655 0.07885 0.28149 0.06405 58617.112379 0.000388 0.18995 0.04712 1.00000 0 1.91805 0.19250 1.56876 0.15744 0.36433 0.08265 0.29519 0.06697 58617.113175 0.000408 0.15976 0.03901 0.98582 0 2.17909 0.19672 1.78684 0.16130 0.34814 0.07898 0.28457 0.06456 58617.114043 0.000460 0.16573 0.04056 0.94969 0 1.92163 0.17647 1.57736 0.14486 0.31846 0.07225 0.26195 0.05943 58617.115149 0.000645 0.11906 0.02822 0.96861 0 1.90482 0.14966 1.55911 0.12250 0.22680 0.05071 0.18549 0.04148 58617.116373 0.000573 0.11455 0.02778 0.96465 0 2.16891 0.16552 1.78626 0.13632 0.24844 0.05719 0.20442 0.04706 58617.117501 0.000556 0.14523 0.03400 0.98958 0 1.85084 0.15691 1.52387 0.12919 0.26879 0.05866 0.22142 0.04832
