/* ** ** 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 55696.529919 0.000778 0.32948 0.02705 0.98513 0 5.24252 0.21357 4.59031 0.18701 1.72730 0.12313 1.51141 0.10773 55696.531467 0.000770 0.31316 0.02577 0.98496 0 5.46690 0.21851 4.83192 0.19313 1.71199 0.12314 1.51316 0.10884 55696.533201 0.000964 0.26909 0.02162 0.98498 0 5.12481 0.19062 4.52705 0.16839 1.37904 0.09822 1.21817 0.08676 55696.534963 0.000799 0.32648 0.02670 0.97464 0 5.16854 0.21034 4.54448 0.18492 1.68744 0.11972 1.48561 0.10539 55696.536601 0.000839 0.31836 0.02616 0.97931 0 4.98387 0.20071 4.38523 0.17659 1.58668 0.11367 1.39619 0.10003 55696.538840 0.001400 0.33708 0.02089 0.98554 0 5.04831 0.15660 4.44655 0.13793 1.70166 0.09128 1.49846 0.08037
