/* ** ** 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 56616.786809 0.000521 0.16665 0.01319 1.00000 0 14.78989 0.43774 13.04882 0.38622 2.46467 0.18098 2.17562 0.15977 56616.787909 0.000579 0.14942 0.01192 0.99000 0 14.79988 0.41740 13.05528 0.36817 2.21133 0.16506 1.94910 0.14549 56616.788959 0.000472 0.19558 0.01572 0.99387 0 13.93596 0.44908 12.31084 0.39670 2.72562 0.20068 2.40498 0.17709 56616.789917 0.000486 0.19250 0.01507 1.00000 0 13.94012 0.43969 12.26952 0.38695 2.68348 0.19231 2.36298 0.16935 56616.790892 0.000489 0.18710 0.01475 0.98817 0 14.29232 0.44384 12.65343 0.39294 2.67407 0.19376 2.36705 0.17150 56616.791904 0.000524 0.17326 0.01353 0.98895 0 14.48079 0.43273 12.73363 0.38051 2.50898 0.18101 2.20747 0.15928 56616.793007 0.000579 0.15587 0.01209 0.99000 0 14.60251 0.41063 12.87208 0.36196 2.27613 0.16446 2.00657 0.14500 56616.794185 0.000599 0.15475 0.01200 0.99517 0 14.06879 0.39684 12.45879 0.35143 2.17716 0.15733 1.92864 0.13937 56616.795296 0.000512 0.17954 0.01452 0.99435 0 13.83882 0.43058 12.22396 0.38031 2.48457 0.18541 2.19273 0.16368 56616.796803 0.000995 0.16972 0.00989 0.98547 0 14.27329 0.31200 12.56738 0.27468 2.42242 0.13087 2.13263 0.11525
