/* ** ** 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 54950.956036 0.000310 0.18169 0.01413 0.99065 0 22.59772 0.68652 20.66858 0.62786 4.10568 0.29382 3.75851 0.26895 54950.956681 0.000336 0.17177 0.01342 1.00000 0 21.64590 0.64482 19.86244 0.59166 3.71818 0.26866 3.40998 0.24638 54950.957367 0.000350 0.15721 0.01224 0.99174 0 22.85732 0.64999 20.87123 0.59343 3.59341 0.26036 3.27962 0.23758 54950.958036 0.000318 0.17304 0.01344 1.00000 0 22.44862 0.66941 20.82420 0.62097 3.88459 0.27869 3.60363 0.25853 54950.958672 0.000318 0.18153 0.01401 0.98182 0 22.20851 0.66949 20.38309 0.61441 4.03143 0.28645 3.69671 0.26266 54950.959341 0.000350 0.16140 0.01247 0.99174 0 22.29645 0.63909 20.60194 0.59049 3.59869 0.25815 3.32486 0.23845 54950.960029 0.000339 0.16903 0.01326 0.97436 0 22.05804 0.64472 20.36199 0.59514 3.72837 0.27147 3.43975 0.25039 54950.960689 0.000321 0.17691 0.01414 1.00000 0 21.37831 0.65384 19.73246 0.60349 3.78195 0.27938 3.49426 0.25812 54950.961328 0.000318 0.18133 0.01426 0.99091 0 21.60294 0.66015 19.92654 0.60889 3.91723 0.28375 3.61059 0.26155 54950.961965 0.000318 0.17966 0.01406 0.99091 0 21.84241 0.66519 20.15003 0.61359 3.92430 0.28296 3.62364 0.26123 54950.962593 0.000310 0.18209 0.01422 0.99065 0 22.31767 0.68184 20.58801 0.62897 4.06377 0.29217 3.74509 0.26929 54950.963206 0.000304 0.19586 0.01532 0.99048 0 21.21598 0.67058 19.56100 0.61823 4.15541 0.29737 3.83079 0.27412 54950.963846 0.000336 0.16736 0.01315 0.98276 0 22.32240 0.65341 20.60419 0.60309 3.73579 0.27250 3.44484 0.25132 54950.964485 0.000304 0.18764 0.01486 0.99048 0 21.65704 0.67481 20.09477 0.62613 4.06363 0.29581 3.77049 0.27447 54950.965142 0.000353 0.16142 0.01241 0.98361 0 22.13457 0.63214 20.53797 0.58654 3.57289 0.25509 3.31518 0.23669 54950.965874 0.000379 0.14113 0.01096 0.99237 0 23.03429 0.62122 21.37249 0.57640 3.25091 0.23665 3.01639 0.21958 54950.966589 0.000336 0.16537 0.01275 1.00000 0 22.35193 0.65177 20.73850 0.60473 3.69633 0.26390 3.42950 0.24485 54950.967257 0.000333 0.18326 0.01415 0.98261 0 20.91349 0.63316 19.40404 0.58746 3.83260 0.27225 3.55600 0.25260 54950.967900 0.000310 0.18550 0.01456 1.00000 0 21.44806 0.66479 19.89914 0.61678 3.97868 0.28682 3.69137 0.26611 54950.968814 0.000605 0.17322 0.01003 0.99522 0 21.71638 0.48021 20.01242 0.44248 3.76176 0.20133 3.46354 0.18540
