/* ** ** 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 55694.564685 0.000498 0.09703 0.01438 0.97093 0 6.86781 0.30349 6.17411 0.27281 0.66637 0.09424 0.59980 0.08482 55694.565637 0.000454 0.10142 0.01507 1.00000 0 7.02409 0.32067 6.29462 0.28732 0.71240 0.10076 0.63801 0.09023 55694.566543 0.000451 0.09947 0.01494 0.98077 0 7.24305 0.32478 6.51139 0.29194 0.72048 0.10327 0.64780 0.09284 55694.567367 0.000373 0.12169 0.01847 0.98450 0 7.24985 0.36166 6.42516 0.32055 0.88222 0.12643 0.78042 0.11185 55694.568343 0.000602 0.07433 0.01118 0.97597 0 7.32724 0.28798 6.49640 0.25532 0.54462 0.07910 0.48305 0.07017 55694.569419 0.000475 0.10156 0.01515 0.96951 0 7.10357 0.31750 6.32704 0.28277 0.72142 0.10269 0.64193 0.09134 55694.570325 0.000431 0.11337 0.01677 1.00000 0 6.81512 0.32476 6.04781 0.28817 0.77260 0.10819 0.68571 0.09602 55694.571251 0.000495 0.09216 0.01384 0.98830 0 7.27371 0.31620 6.42366 0.27923 0.67037 0.09638 0.59209 0.08511 55694.572194 0.000448 0.10642 0.01589 0.99355 0 6.96843 0.32461 6.17793 0.28778 0.74158 0.10518 0.65660 0.09315 55694.573154 0.000512 0.08418 0.01306 0.99435 0 7.31152 0.30976 6.48724 0.27482 0.61546 0.09187 0.54518 0.08137 55694.574101 0.000434 0.10632 0.01603 1.00000 0 6.87720 0.32282 6.20820 0.29141 0.73120 0.10479 0.66075 0.09470 55694.574943 0.000408 0.12191 0.01825 0.95745 0 6.87036 0.33732 6.09274 0.29913 0.83758 0.11846 0.74198 0.10493 55694.575831 0.000480 0.10188 0.01512 0.97590 0 6.85588 0.30934 6.07908 0.27428 0.69848 0.09878 0.61831 0.08744 55694.576719 0.000408 0.12404 0.01865 0.97872 0 6.58652 0.32671 5.90687 0.29298 0.81700 0.11593 0.73273 0.10395 55694.577799 0.000671 0.07655 0.01055 0.98276 0 7.47535 0.27471 6.59320 0.24229 0.57222 0.07601 0.50500 0.06708
