/* ** ** 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 55220.277582 0.000356 0.25408 0.02176 0.97561 0 32.26756 1.19819 12.47444 0.46193 8.19840 0.63277 3.15731 0.24299 55220.278317 0.000379 0.23743 0.01929 0.99237 0 34.59976 1.23541 12.76350 0.45550 8.21495 0.59954 3.02707 0.22073 55220.279066 0.000370 0.26019 0.02158 0.99219 0 32.92895 1.23994 11.80306 0.44440 8.56793 0.63325 3.06975 0.22687 55220.279853 0.000417 0.22506 0.01861 0.98611 0 33.45767 1.17328 12.08434 0.42378 7.52989 0.56403 2.71971 0.20372 55220.280620 0.000350 0.26534 0.02208 1.00000 0 33.46685 1.26673 12.07504 0.45705 8.88017 0.65807 3.20542 0.23754 55220.281320 0.000350 0.26679 0.02195 0.99174 0 33.78713 1.27486 12.22962 0.46145 9.01419 0.65908 3.26263 0.23855 55220.282035 0.000365 0.24181 0.01994 0.99206 0 35.40866 1.28212 12.83717 0.46483 8.56207 0.63442 3.10284 0.22994 55220.282773 0.000373 0.25842 0.02139 0.98450 0 32.80195 1.22314 11.88031 0.44296 8.47677 0.62656 3.06975 0.22687 55220.283482 0.000336 0.29273 0.02431 0.99138 0 32.32812 1.28490 11.68880 0.46457 9.46336 0.69011 3.42191 0.24953 55220.284202 0.000385 0.23713 0.01945 0.97744 0 35.00995 1.24673 12.64731 0.45035 8.30192 0.61349 2.99891 0.22163 55220.284969 0.000382 0.22986 0.01886 0.98485 0 35.86775 1.26333 12.98722 0.45743 8.24450 0.61095 2.98350 0.22109 55220.285715 0.000365 0.25148 0.02077 0.97619 0 34.64004 1.26298 12.54177 0.45726 8.71120 0.64547 3.15330 0.23368 55220.286459 0.000379 0.24798 0.02010 0.97710 0 34.11080 1.22906 12.38567 0.44628 8.45882 0.61427 3.07302 0.22318 55220.287168 0.000330 0.26602 0.02206 0.98246 0 36.08949 1.37956 13.08109 0.50004 9.60042 0.70666 3.47934 0.25611 55220.287857 0.000359 0.26328 0.02147 0.96774 0 34.37900 1.27611 12.44327 0.46188 9.05144 0.65737 3.27788 0.23806 55220.288571 0.000356 0.24416 0.02012 0.98374 0 36.07462 1.29941 13.12790 0.47285 8.80789 0.65278 3.20542 0.23754 55220.289581 0.000654 0.24826 0.01532 0.98230 0 35.61102 0.95561 12.93071 0.34698 8.84095 0.49133 3.21010 0.17837
