/* ** ** 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 59992.411775 0.000402 0.12044 0.00943 0.99281 0 26.60226 0.66762 23.41587 0.58768 3.20404 0.23765 2.81981 0.20913 59992.412533 0.000356 0.13286 0.01036 0.98374 0 27.70732 0.72520 24.45966 0.64018 3.68122 0.27036 3.24852 0.23855 59992.413268 0.000379 0.12715 0.00969 1.00000 0 27.02216 0.69447 23.81796 0.61213 3.43592 0.24645 3.02900 0.21728 59992.414070 0.000422 0.11455 0.00867 0.98630 0 27.31420 0.66280 24.05105 0.58363 3.12891 0.22442 2.75555 0.19766 59992.414845 0.000353 0.13880 0.01100 1.00000 0 25.91350 0.70783 22.86059 0.62444 3.59680 0.26748 3.17320 0.23598 59992.415563 0.000365 0.13939 0.01071 0.97619 0 26.24169 0.70152 23.14538 0.61875 3.65787 0.26359 3.22658 0.23251 59992.416335 0.000408 0.12030 0.00911 0.97872 0 27.20943 0.67266 24.02282 0.59388 3.27330 0.23420 2.88987 0.20676 59992.417114 0.000370 0.12175 0.00961 1.00000 0 28.21726 0.72104 24.82555 0.63440 3.43543 0.25668 3.02500 0.22597 59992.417857 0.000373 0.13594 0.01059 1.00000 0 25.40297 0.68278 22.41078 0.60236 3.45319 0.25244 3.04652 0.22271 59992.418650 0.000420 0.11699 0.00916 1.00000 0 26.08169 0.65219 22.94009 0.57364 3.05133 0.22632 2.68368 0.19903 59992.419437 0.000367 0.13385 0.01048 1.00000 0 26.20190 0.69718 23.01704 0.61243 3.50716 0.25821 3.07927 0.22673 59992.420320 0.000515 0.15363 0.00939 0.99438 0 26.87768 0.59521 23.74700 0.52588 4.12928 0.23537 3.64763 0.20792
