/* ** ** 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 57496.068424 0.000304 0.22853 0.03597 1.00000 0 4.66789 0.31787 4.21592 0.28710 1.06674 0.15135 0.96286 0.13663 57496.069692 0.000964 0.27372 0.02202 0.97898 0 4.90911 0.18376 4.46728 0.16722 1.34370 0.09566 1.22247 0.08703 57496.071711 0.001056 0.23576 0.01864 0.98082 0 5.21524 0.18112 4.74664 0.16485 1.22957 0.08731 1.11880 0.07945 57496.073763 0.000995 0.24919 0.02012 0.97384 0 5.15837 0.18412 4.71010 0.16812 1.28540 0.09308 1.17366 0.08499 57496.075731 0.000972 0.25941 0.02072 0.97619 0 5.15272 0.18659 4.67956 0.16946 1.33665 0.09516 1.21502 0.08650 57496.078280 0.001577 0.24090 0.01546 0.98349 0 5.20348 0.14725 4.73160 0.13389 1.25351 0.07222 1.14119 0.06575
