/* ** ** 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 60019.039125 0.000486 0.11984 0.00917 0.98214 0 21.99626 0.54120 20.01796 0.49249 2.63608 0.19088 2.39401 0.17338 60019.040074 0.000463 0.12519 0.00958 0.98750 0 21.88878 0.55492 19.95706 0.50591 2.74028 0.19792 2.49709 0.18036 60019.041041 0.000503 0.11121 0.00849 0.99425 0 22.44694 0.53897 20.52930 0.49292 2.49639 0.18079 2.28331 0.16536 60019.041987 0.000443 0.12540 0.00959 0.98039 0 23.01819 0.57969 20.99318 0.52868 2.88660 0.20850 2.63027 0.18998 60019.042936 0.000506 0.11368 0.00858 0.98857 0 22.09318 0.53383 20.21732 0.48851 2.51154 0.17948 2.29829 0.16424 60019.043911 0.000469 0.12617 0.00967 0.99383 0 21.31721 0.54614 19.43395 0.49787 2.68955 0.19424 2.45056 0.17700 60019.044898 0.000518 0.11242 0.00864 0.97765 0 21.74391 0.52047 19.89832 0.47629 2.44449 0.17845 2.23701 0.16331 60019.046322 0.000906 0.10883 0.00638 0.97689 0 21.78940 0.39536 19.89926 0.36106 2.37127 0.13225 2.16636 0.12083
