/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 56659.487531 0.000327 0.16079 0.01248 1.00000 0 23.77043 0.68448 21.80904 0.62796 3.82197 0.27546 3.50893 0.25282 56659.488147 0.000289 0.19662 0.01524 1.00000 0 22.11328 0.70120 20.50352 0.65015 4.34783 0.30753 4.03133 0.28514 56659.488706 0.000269 0.20058 0.01547 1.00000 0 23.50757 0.75197 21.80063 0.69737 4.71522 0.33094 4.37286 0.30691 56659.489290 0.000315 0.17025 0.01329 0.99083 0 23.28492 0.68926 21.59017 0.63909 3.96426 0.28641 3.67567 0.26556 56659.489912 0.000307 0.16552 0.01287 1.00000 0 24.36468 0.71401 22.59887 0.66227 4.03292 0.29057 3.74065 0.26952 56659.490529 0.000310 0.18047 0.01384 0.98131 0 23.04040 0.69331 21.22845 0.63875 4.15813 0.29330 3.83495 0.27050 56659.491145 0.000307 0.17926 0.01378 1.00000 0 23.01740 0.69167 21.23388 0.63805 4.12607 0.29189 3.80314 0.26900 56659.491738 0.000286 0.18830 0.01477 1.00000 0 22.98368 0.72174 21.24743 0.66719 4.32776 0.31099 4.00046 0.28744 56659.492551 0.000527 0.16746 0.01018 0.99506 0 23.48894 0.53592 21.60929 0.49301 3.93349 0.22151 3.61814 0.20377 56659.554088 0.000217 0.21990 0.01773 1.00000 0 26.25864 0.88815 24.11681 0.81571 5.77423 0.42249 5.30343 0.38805 56659.554556 0.000252 0.17362 0.01338 0.98851 0 29.23346 0.86493 26.79474 0.79277 5.07551 0.36125 4.65064 0.33101 56659.555025 0.000217 0.20621 0.01616 0.98667 0 28.72970 0.93078 26.06775 0.84451 5.92441 0.42278 5.37773 0.38373 56659.555471 0.000229 0.20932 0.01665 0.98734 0 26.47138 0.86769 24.16590 0.79210 5.54096 0.40163 5.05803 0.36662 56659.555913 0.000214 0.22004 0.01736 0.98649 0 27.74807 0.92726 24.97833 0.83463 6.10569 0.43628 5.49654 0.39277 56659.556339 0.000211 0.20616 0.01631 1.00000 0 28.91585 0.94057 26.48669 0.86154 5.96123 0.42989 5.45936 0.39364 56659.556784 0.000234 0.19200 0.01510 1.00000 0 27.68793 0.87641 25.41321 0.80441 5.31614 0.38282 4.87948 0.35137 56659.557250 0.000231 0.19401 0.01527 1.00000 0 27.75261 0.88220 25.46495 0.80948 5.38427 0.38772 4.94047 0.35576 56659.557710 0.000229 0.19343 0.01530 1.00000 0 28.50097 0.90503 25.87676 0.82165 5.51295 0.39951 4.99401 0.36198 56659.558165 0.000226 0.21249 0.01667 1.00000 0 26.40705 0.87173 24.14152 0.79688 5.61117 0.39943 5.12763 0.36496 56659.558700 0.000310 0.19165 0.01317 1.00000 0 27.87783 0.76433 25.58544 0.70148 5.34289 0.33653 4.90353 0.30886
