/* ** ** 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 56076.020764 0.000556 0.39416 0.03348 0.97396 0 6.45315 0.28915 5.35945 0.24008 2.54355 0.18357 2.11467 0.15258 56076.021895 0.000576 0.37785 0.03171 0.96985 0 6.38030 0.27884 5.44596 0.23800 2.41077 0.17270 2.05460 0.14718 56076.023064 0.000593 0.36951 0.03083 0.96098 0 6.46276 0.27776 5.49186 0.23600 2.38804 0.17079 2.02798 0.14501 56076.024242 0.000584 0.37525 0.03170 0.97525 0 6.26083 0.27528 5.33792 0.23470 2.34935 0.16946 2.00240 0.14439 56076.025683 0.000856 0.40242 0.02731 0.98680 0 6.27827 0.22912 5.32165 0.19421 2.52651 0.14457 2.14235 0.12257 56076.088552 0.000518 0.37542 0.03212 0.96648 0 6.66093 0.29295 5.99369 0.26361 2.50067 0.18351 2.24879 0.16501 56076.089646 0.000576 0.34240 0.02858 0.98995 0 6.54903 0.27757 5.85105 0.24797 2.24241 0.16124 2.00702 0.14431 56076.090859 0.000637 0.31761 0.02595 0.98636 0 6.41159 0.25711 5.78260 0.23189 2.03641 0.14496 1.83665 0.13074 56076.092363 0.000868 0.32871 0.02180 0.99000 0 6.96587 0.23079 6.26223 0.20748 2.28974 0.13154 2.06011 0.11835
