/* ** ** 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 59783.756400 0.000611 0.27280 0.02200 0.99526 0 7.65629 0.28997 6.95429 0.26339 2.08867 0.14870 1.89774 0.13510 59783.757711 0.000700 0.22934 0.01839 1.00000 0 7.78291 0.27101 7.12008 0.24793 1.78496 0.12893 1.63296 0.11795 59783.759076 0.000666 0.25761 0.02095 0.96522 0 7.51500 0.27386 6.87308 0.25047 1.93590 0.14079 1.77043 0.12875 59783.760781 0.001039 0.28621 0.01807 0.98010 0 7.14979 0.21251 6.53953 0.19437 2.04631 0.11398 1.87163 0.10425 59783.829243 0.000634 0.29816 0.02448 0.98630 0 7.16556 0.28356 6.15575 0.24364 2.13649 0.15371 1.83506 0.13203 59783.830539 0.000663 0.26876 0.02213 0.99127 0 7.35964 0.27861 6.39538 0.24211 1.97796 0.14461 1.71883 0.12566 59783.832623 0.001421 0.25518 0.01458 0.97352 0 7.32225 0.18946 6.36319 0.16464 1.86847 0.09522 1.62374 0.08275
