/* ** ** 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 56772.071189 0.000356 0.32684 0.05031 0.98374 0 5.47799 0.42632 2.94416 0.22645 1.79041 0.23781 0.98067 0.12846 56772.071959 0.000414 0.27097 0.04403 0.96503 0 6.18439 0.46679 2.63446 0.19888 1.67576 0.24113 0.71470 0.10285 56772.072812 0.000440 0.24618 0.03933 0.94737 0 6.41652 0.45402 2.80489 0.19833 1.57960 0.22623 0.68848 0.09850 56772.073880 0.000628 0.19732 0.03143 0.94931 0 5.52673 0.35645 2.40754 0.15527 1.09055 0.15881 0.47380 0.06899 56772.074858 0.000350 0.35869 0.06014 0.96694 0 5.38441 0.46344 2.34935 0.20220 1.93134 0.27787 0.84298 0.12131 56772.075529 0.000321 0.37526 0.06383 0.99099 0 5.66183 0.51196 2.41633 0.21849 2.12465 0.30612 0.90551 0.13048 56772.076415 0.000564 0.20716 0.03400 0.94872 0 5.75016 0.38314 2.48133 0.16528 1.19123 0.17866 0.51372 0.07707 56772.077352 0.000373 0.35054 0.05819 0.93798 0 5.41736 0.45596 2.34145 0.19707 1.89899 0.27169 0.81935 0.11723 56772.078128 0.000402 0.27010 0.04384 0.95683 0 6.36263 0.47748 2.73647 0.20535 1.71855 0.24737 0.74157 0.10672 56772.079048 0.000518 0.23023 0.03652 0.97207 0 5.69254 0.38967 2.46920 0.16901 1.31061 0.18756 0.56978 0.08152 56772.079919 0.000353 0.35091 0.05842 0.99180 0 5.38939 0.46605 2.36076 0.20404 1.89121 0.26901 0.82359 0.11715 56772.080645 0.000373 0.32254 0.05388 0.93798 0 5.85707 0.47857 2.48700 0.20316 1.88913 0.27527 0.80663 0.11746 56772.081464 0.000446 0.35852 0.05420 0.96753 0 5.27494 0.41829 2.27480 0.18020 1.89116 0.24340 0.81672 0.10507
