/* ** ** 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 56695.363402 0.000796 0.12074 0.00915 0.98545 0 13.84391 0.34309 12.13010 0.30063 1.67158 0.11976 1.46511 0.10497 56695.365023 0.000825 0.12037 0.00907 0.99649 0 13.24621 0.32756 11.66771 0.28852 1.59448 0.11349 1.40442 0.09996 56695.366692 0.000845 0.11281 0.00853 0.99315 0 13.78692 0.33200 12.13848 0.29230 1.55529 0.11143 1.36912 0.09809 56695.368402 0.000865 0.10760 0.00811 0.98997 0 14.16092 0.33249 12.46575 0.29269 1.52373 0.10917 1.34137 0.09610 56695.369927 0.000660 0.14663 0.01160 0.99123 0 13.50873 0.37672 11.71466 0.32671 1.98073 0.14669 1.71677 0.12714 56695.371403 0.000816 0.11275 0.00879 0.98582 0 14.16320 0.34545 12.37768 0.30188 1.59687 0.11830 1.39565 0.10336 56695.373252 0.001033 0.12578 0.00815 0.99160 0 14.31097 0.30807 12.41834 0.26733 1.80008 0.10997 1.56464 0.09555
