/* ** ** 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 57422.134018 0.000411 0.11085 0.02732 0.96479 0 8.30174 0.64651 2.53488 0.19737 0.92024 0.21521 0.28118 0.06572 57422.135062 0.000634 0.07893 0.01889 0.94977 0 7.88630 0.51270 2.37468 0.15437 0.62245 0.14334 0.18767 0.04322 57422.136263 0.000567 0.08131 0.01949 0.96429 0 8.45950 0.56411 2.54067 0.16942 0.68786 0.15839 0.20654 0.04756 57422.137267 0.000437 0.11549 0.02767 0.96026 0 7.85365 0.60358 2.36377 0.18167 0.90706 0.20580 0.27277 0.06189 57422.138294 0.000590 0.09286 0.02206 0.97059 0 7.17648 0.50547 2.15197 0.15158 0.66638 0.15121 0.19975 0.04532 57422.139570 0.000686 0.12475 0.02273 0.96459 0 7.88053 0.48442 2.38609 0.14667 0.98314 0.16861 0.29795 0.05110
