/* ** ** 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 55949.397158 0.000396 0.09769 0.01485 0.98540 0 8.68556 0.38858 7.42374 0.33211 0.84847 0.12329 0.72618 0.10552 55949.397905 0.000350 0.10168 0.01550 0.99174 0 9.37875 0.43143 8.02468 0.36911 0.95365 0.13857 0.81696 0.11871 55949.398596 0.000341 0.11296 0.01752 0.98305 0 8.60833 0.41757 7.40055 0.35898 0.97237 0.14325 0.83594 0.12315 55949.399294 0.000356 0.10340 0.01577 0.99187 0 9.04003 0.41804 7.77155 0.35938 0.93472 0.13583 0.80357 0.11677 55949.400003 0.000353 0.11154 0.01663 0.97541 0 8.77703 0.41331 7.54657 0.35537 0.97899 0.13845 0.84174 0.11904 55949.400720 0.000365 0.10533 0.01588 0.97619 0 8.89747 0.41449 7.64962 0.35636 0.93715 0.13434 0.80570 0.11549 55949.401467 0.000382 0.09679 0.01509 0.96212 0 9.07490 0.40530 7.80150 0.34843 0.87839 0.13121 0.75514 0.11280 55949.402181 0.000333 0.11085 0.01655 1.00000 0 9.14043 0.43657 7.85777 0.37531 1.01320 0.14329 0.87102 0.12318 55949.402879 0.000365 0.09920 0.01509 0.96825 0 9.42255 0.42516 8.10025 0.36550 0.93474 0.13583 0.80357 0.11677 55949.403660 0.000417 0.09712 0.01457 0.96528 0 8.53952 0.37737 7.34116 0.32441 0.82934 0.11888 0.71296 0.10220 55949.404496 0.000420 0.09027 0.01372 0.98621 0 8.91918 0.38300 7.66759 0.32925 0.80509 0.11734 0.69211 0.10088 55949.405272 0.000356 0.11984 0.01804 0.98374 0 8.18593 0.40066 7.03714 0.34443 0.98099 0.13963 0.84332 0.12004 55949.406065 0.000437 0.08704 0.01300 0.98675 0 8.88875 0.37451 7.64135 0.32195 0.77368 0.11090 0.66511 0.09534 55949.407066 0.000564 0.10195 0.01296 0.97949 0 8.42561 0.32145 7.24322 0.27634 0.85898 0.10414 0.73844 0.08952
