/* ** ** 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 56485.975394 0.000420 0.33566 0.02785 1.00000 0 9.63359 0.40218 8.15765 0.34056 3.23363 0.23183 2.74125 0.19653 56485.976219 0.000405 0.41134 0.03514 0.97857 0 8.34085 0.38394 7.05050 0.32455 3.43095 0.24694 2.90079 0.20879 56485.977087 0.000463 0.36566 0.03047 0.98750 0 8.35310 0.36095 7.02005 0.30333 3.05443 0.21762 2.56596 0.18281 56485.978019 0.000469 0.33532 0.02799 0.98148 0 8.75590 0.36403 7.38069 0.30684 2.93604 0.21249 2.47422 0.17902 56485.978959 0.000472 0.33739 0.02805 0.98160 0 8.83761 0.36856 7.34328 0.30622 2.98172 0.21450 2.47777 0.17822 56485.979879 0.000448 0.34215 0.02845 1.00000 0 9.00798 0.37877 7.50898 0.31572 3.08208 0.22114 2.57062 0.18443 56485.980820 0.000492 0.35084 0.02895 0.98235 0 8.22207 0.34530 6.85449 0.28785 2.88463 0.20493 2.40455 0.17083 56485.981754 0.000443 0.35729 0.02998 0.98693 0 8.69885 0.37307 7.31147 0.31349 3.10802 0.22415 2.61218 0.18838 56485.982753 0.000556 0.32618 0.02581 0.98151 0 8.35904 0.32720 7.02933 0.27512 2.72657 0.18746 2.28993 0.15744
