/* ** ** 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 59264.023202 0.000926 0.11863 0.00931 0.97500 0 11.48347 0.28538 10.42926 0.25916 1.36225 0.10143 1.23864 0.09222 59264.025106 0.000972 0.11992 0.00903 0.98512 0 10.98860 0.27101 10.04548 0.24775 1.31776 0.09378 1.20511 0.08576 59264.027039 0.000961 0.12356 0.00931 0.99699 0 10.72345 0.26966 9.80919 0.24666 1.32502 0.09406 1.21116 0.08597 59264.028966 0.000966 0.11609 0.00889 0.99401 0 11.14484 0.27330 10.21146 0.25041 1.29378 0.09386 1.18543 0.08600 59264.030250 0.000318 0.08736 0.01290 1.00000 0 11.37538 0.48466 10.42346 0.44410 0.99377 0.14054 0.91061 0.12878 59264.030861 0.000292 0.09483 0.01408 1.00000 0 11.41350 0.51489 10.45806 0.47179 1.08235 0.15307 0.99175 0.14025 59264.031544 0.000391 0.08707 0.01235 0.97037 0 11.18221 0.43335 10.24630 0.39708 0.97366 0.13285 0.89217 0.12173
