/* ** ** 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 57498.458376 0.000304 0.25806 0.04159 0.96190 0 5.80608 0.41791 3.86380 0.27702 1.49833 0.21605 0.97644 0.14053 57498.459747 0.001068 0.27611 0.02219 0.97832 0 5.55247 0.20734 4.00224 0.14938 1.53307 0.10908 1.10417 0.07853 57498.461903 0.001088 0.29313 0.02369 0.98670 0 5.02709 0.19481 3.67480 0.14240 1.47357 0.10451 1.07719 0.07639 57498.463972 0.000981 0.31231 0.02550 0.96460 0 5.29935 0.20960 3.89729 0.15411 1.65505 0.11825 1.21424 0.08674 57498.465934 0.000981 0.27676 0.02235 0.97935 0 5.92934 0.22322 4.32936 0.16297 1.64101 0.11725 1.19596 0.08543 57498.468159 0.001244 0.26795 0.01963 0.98140 0 5.70980 0.19301 4.21230 0.14239 1.52995 0.09946 1.12970 0.07343
