/* ** ** 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 56019.456458 0.000657 0.34156 0.02813 0.99119 0 5.92113 0.24719 5.21095 0.21755 2.02242 0.14358 1.78045 0.12640 56019.457699 0.000584 0.34800 0.02900 1.00000 0 6.39525 0.27224 5.64076 0.24012 2.22555 0.15943 1.96302 0.14063 56019.458975 0.000692 0.30420 0.02480 0.98326 0 6.30457 0.24787 5.56142 0.21866 1.91782 0.13694 1.69176 0.12080 56019.460347 0.000680 0.31417 0.02576 0.99149 0 6.15681 0.24829 5.43086 0.21902 1.93431 0.13812 1.70628 0.12184 56019.461678 0.000651 0.34012 0.02825 1.00000 0 5.87365 0.24688 5.18147 0.21779 1.99773 0.14311 1.76236 0.12625 56019.462959 0.000631 0.37282 0.03161 0.98165 0 5.57510 0.24437 4.91823 0.21557 2.07850 0.15087 1.83361 0.13309 56019.464395 0.000804 0.28006 0.02309 0.98561 0 5.76719 0.22033 5.08646 0.19432 1.61518 0.11802 1.42454 0.10409 56019.465934 0.000735 0.31457 0.02579 0.97638 0 5.80395 0.23274 5.12070 0.20535 1.82577 0.13055 1.61090 0.11519
