/* ** ** 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 59024.924054 0.000535 0.22710 0.03561 0.97297 0 2.83983 0.19223 2.44958 0.16581 0.64493 0.09121 0.55648 0.07870 59024.925061 0.000472 0.25298 0.04024 0.98773 0 2.88334 0.20830 2.48318 0.17939 0.72942 0.10336 0.62797 0.08898 59024.926183 0.000645 0.20029 0.03161 0.96861 0 2.64683 0.17060 2.27977 0.14694 0.53014 0.07636 0.45633 0.06572 59024.927185 0.000356 0.29293 0.04808 0.95935 0 3.29630 0.25401 2.84479 0.21922 0.96558 0.13992 0.83080 0.12039 59024.927957 0.000417 0.27952 0.04483 0.97917 0 2.93669 0.22223 2.54144 0.19232 0.82086 0.11609 0.71040 0.10047 59024.928843 0.000469 0.20868 0.03279 0.97531 0 3.48803 0.22619 3.00672 0.19498 0.72789 0.10419 0.62722 0.08978 59024.929745 0.000434 0.23966 0.03792 0.97333 0 3.34978 0.23195 2.84507 0.19698 0.80280 0.11423 0.68242 0.09709 59024.930770 0.000590 0.18142 0.02844 0.98039 0 3.14091 0.19431 2.71731 0.16811 0.56982 0.08206 0.49284 0.07098 59024.931753 0.000394 0.28655 0.04648 0.92647 0 3.17089 0.23676 2.73242 0.20400 0.90862 0.13085 0.78228 0.11266 59024.933064 0.000917 0.21157 0.02457 0.96215 0 3.24532 0.15750 2.80864 0.13630 0.68662 0.07246 0.59422 0.06271
