/* ** ** 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 59344.208829 0.000466 0.15849 0.01204 0.98758 0 17.33747 0.48917 15.96555 0.45045 2.74782 0.19382 2.53252 0.17863 59344.209776 0.000480 0.14586 0.01135 0.98795 0 17.72440 0.48643 16.39069 0.44979 2.58529 0.18830 2.39008 0.17410 59344.210722 0.000466 0.14309 0.01115 0.99379 0 18.53382 0.50484 17.13733 0.46679 2.65208 0.19368 2.45330 0.17912 59344.211703 0.000515 0.14120 0.01099 0.98876 0 17.14240 0.46218 15.80828 0.42619 2.42048 0.17671 2.23027 0.16284 59344.212773 0.000556 0.13277 0.01009 0.98958 0 17.32176 0.45144 15.76360 0.41081 2.29976 0.16424 2.09352 0.14950 59344.213838 0.000509 0.14575 0.01119 0.98864 0 17.12886 0.46826 15.62702 0.42718 2.49658 0.17917 2.27770 0.16346 59344.214920 0.000573 0.13255 0.01006 0.98990 0 16.81592 0.43884 15.36247 0.40092 2.22903 0.15881 2.03966 0.14529 59344.216052 0.000558 0.13603 0.01036 0.98964 0 16.76255 0.44445 15.30921 0.40590 2.28020 0.16284 2.08256 0.14872 59344.217093 0.000483 0.15644 0.01253 1.00000 0 16.10940 0.46674 14.73104 0.42677 2.52015 0.18824 2.30376 0.17207 59344.218118 0.000541 0.13698 0.01073 0.98396 0 16.73468 0.44809 15.44350 0.41348 2.29233 0.16869 2.11454 0.15558 59344.219217 0.000558 0.13071 0.00997 0.98964 0 17.54036 0.45368 15.97765 0.41326 2.29262 0.16446 2.08836 0.14984 59344.220632 0.000856 0.13440 0.00823 0.98986 0 17.19258 0.36407 15.69079 0.33228 2.31064 0.13271 2.10663 0.12098
