/* ** ** 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 54914.938903 0.000512 0.14943 0.01155 0.97740 0 18.76811 0.51423 15.22798 0.41723 2.80447 0.20275 2.27631 0.16457 54914.939997 0.000582 0.13740 0.01050 0.97512 0 18.47684 0.48544 14.69023 0.38594 2.53868 0.18221 2.02087 0.14502 54914.941146 0.000567 0.13523 0.01027 0.98980 0 19.22482 0.50208 15.21806 0.39743 2.59970 0.18540 2.05793 0.14676 54914.942390 0.000677 0.10991 0.00831 0.98718 0 19.58868 0.46327 15.58825 0.36863 2.15298 0.15451 1.71468 0.12305 54914.943703 0.000637 0.12513 0.00952 0.98182 0 18.37411 0.46247 14.63778 0.36841 2.29918 0.16501 1.83375 0.13159 54914.944901 0.000561 0.13900 0.01059 0.98969 0 18.73842 0.49482 15.04360 0.39724 2.60463 0.18615 2.08831 0.14926 54914.946108 0.000645 0.11937 0.00931 0.98206 0 18.52227 0.46027 14.79818 0.36772 2.21092 0.16339 1.76683 0.13063 54914.947341 0.000587 0.12848 0.00986 0.99507 0 19.07280 0.49033 15.17525 0.39010 2.45052 0.17715 1.94951 0.14094 54914.948463 0.000530 0.15459 0.01187 0.98361 0 17.73727 0.49527 14.28302 0.39881 2.74199 0.19605 2.20686 0.15778 54914.949496 0.000503 0.16247 0.01256 1.00000 0 17.44077 0.50282 14.01676 0.40408 2.83363 0.20334 2.27638 0.16335 54914.950631 0.000631 0.12849 0.00975 0.98165 0 17.91225 0.45484 14.44278 0.36672 2.30153 0.16455 1.85624 0.13271 54914.952346 0.001085 0.13662 0.00759 0.98933 0 18.22746 0.34889 14.78173 0.28294 2.49031 0.12985 2.01954 0.10530
