/* ** ** 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 55309.141037 0.000197 0.24323 0.01946 1.00000 0 26.68136 0.94263 23.97214 0.84688 6.48967 0.46580 5.82761 0.41830 55309.141465 0.000231 0.20998 0.01655 0.97500 0 26.82619 0.87304 24.22834 0.78849 5.63307 0.40423 5.08048 0.36467 55309.141931 0.000234 0.19858 0.01569 1.00000 0 26.69048 0.85906 24.54674 0.79006 5.30015 0.38236 4.87425 0.35163 55309.142371 0.000205 0.23652 0.01865 1.00000 0 26.38668 0.92023 23.85188 0.83183 6.24089 0.44132 5.64320 0.39903 55309.142776 0.000200 0.25401 0.02052 1.00000 0 24.48408 0.88983 22.52625 0.81867 6.21927 0.44866 5.72194 0.41279 55309.143242 0.000266 0.18035 0.01394 1.00000 0 26.35073 0.80096 24.21117 0.73592 4.75246 0.33770 4.36682 0.31030 55309.143748 0.000240 0.20908 0.01620 1.00000 0 26.05147 0.84690 23.48385 0.76340 5.44695 0.38322 4.90623 0.34519 55309.144211 0.000223 0.22775 0.01809 1.00000 0 24.93643 0.85664 22.76170 0.78193 5.67916 0.40664 5.17247 0.37032 55309.144642 0.000208 0.23086 0.01840 1.00000 0 26.40083 0.91358 23.88275 0.82640 6.09495 0.43752 5.50385 0.39506 55309.145091 0.000240 0.18705 0.01463 1.00000 0 27.90059 0.86603 25.51437 0.79190 5.21868 0.37469 4.77442 0.34271 55309.145557 0.000226 0.21869 0.01757 0.98718 0 25.53911 0.86412 23.27467 0.78746 5.58525 0.40705 5.08945 0.37087 55309.146025 0.000243 0.20222 0.01582 1.00000 0 25.77922 0.83398 23.54072 0.76156 5.21309 0.37139 4.75885 0.33902 55309.146506 0.000237 0.19510 0.01549 1.00000 0 27.01342 0.86117 24.61941 0.78477 5.27044 0.38310 4.80355 0.34912 55309.146983 0.000240 0.20445 0.01611 1.00000 0 25.55643 0.83046 23.35319 0.75883 5.22494 0.37510 4.77442 0.34271 55309.147446 0.000223 0.21106 0.01661 1.00000 0 27.14858 0.89689 24.48012 0.80875 5.72992 0.40925 5.16546 0.36892 55309.147900 0.000231 0.20499 0.01618 0.98750 0 27.20202 0.88240 24.50927 0.79504 5.57626 0.40122 5.02300 0.36142 55309.148384 0.000252 0.19195 0.01496 0.97701 0 27.26014 0.84926 24.37790 0.75947 5.23251 0.37371 4.67930 0.33420 55309.148870 0.000234 0.20810 0.01612 0.98765 0 26.48396 0.85860 24.29153 0.78752 5.51118 0.38777 5.05842 0.35591 55309.149538 0.000434 0.20148 0.01176 0.98000 0 26.74656 0.63344 24.26298 0.57455 5.38903 0.28757 4.88729 0.26079
