/* ** ** 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 59309.190637 0.000420 0.28799 0.04754 0.97241 0 4.06772 0.32498 2.37795 0.18642 1.17146 0.16924 0.70676 0.10053 59309.191528 0.000472 0.26298 0.04190 0.96319 0 4.12761 0.30205 2.45181 0.17923 1.08550 0.15364 0.63800 0.09023 59309.192475 0.000475 0.27543 0.04434 0.98171 0 3.83351 0.28887 2.23917 0.16873 1.05586 0.15020 0.61896 0.08804 59309.193539 0.000590 0.21507 0.03434 0.98529 0 3.83410 0.25792 2.25298 0.15151 0.82460 0.11943 0.48812 0.07066 59309.194520 0.000391 0.34356 0.05678 0.97778 0 3.77538 0.31752 2.21078 0.18582 1.29708 0.18455 0.75495 0.10739 59309.195287 0.000376 0.31168 0.05043 0.96154 0 4.37845 0.34418 2.55762 0.20104 1.36468 0.19300 0.80133 0.11333 59309.196100 0.000437 0.31701 0.05208 0.96026 0 3.58847 0.28914 2.15141 0.17330 1.13758 0.16286 0.68372 0.09782 59309.197041 0.000503 0.20036 0.03141 0.97126 0 4.84406 0.31000 2.93312 0.18768 0.97055 0.13889 0.58662 0.08393 59309.197891 0.000347 0.36448 0.06112 0.95000 0 3.99122 0.34850 2.38336 0.20801 1.45471 0.20824 0.86964 0.12442 59309.198617 0.000379 0.27723 0.04443 0.97710 0 4.70047 0.35359 2.83926 0.21341 1.30310 0.18441 0.78255 0.11067 59309.199532 0.000535 0.21111 0.03305 0.97297 0 4.33879 0.28378 2.62426 0.17156 0.91597 0.13030 0.55363 0.07875 59309.200721 0.000654 0.27740 0.03463 0.96903 0 4.44016 0.26015 2.73252 0.16001 1.23172 0.13576 0.75691 0.08337
