/* ** ** 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 58126.756195 0.000408 0.27500 0.01001 1.00000 0 57.23569 0.96515 51.16905 0.86284 15.73981 0.50763 14.06554 0.45379 58126.757017 0.000414 0.26801 0.00973 1.00000 0 57.60474 0.96087 51.95845 0.86661 15.43851 0.49794 13.93180 0.44925 58126.757833 0.000402 0.28204 0.01025 1.00000 0 55.85234 0.95332 50.79371 0.86698 15.75242 0.50529 14.32568 0.45952 58126.758617 0.000382 0.29579 0.01098 1.00000 0 55.61459 0.98100 50.44141 0.88974 16.45022 0.53745 14.92561 0.48764 58126.759375 0.000376 0.29169 0.01070 1.00000 0 57.72979 1.00338 52.38854 0.91050 16.83944 0.54384 15.27875 0.49345 58126.760148 0.000396 0.28815 0.01055 1.00000 0 55.36903 0.96011 50.33976 0.87290 15.95444 0.51420 14.50546 0.46750 58126.760929 0.000385 0.29466 0.01105 1.00000 0 55.38016 0.97821 49.86963 0.88088 16.31809 0.53951 14.69265 0.48563 58126.761705 0.000391 0.28858 0.01064 1.00000 0 55.84528 0.96902 50.75500 0.88070 16.11558 0.52459 14.64593 0.47675 58126.762497 0.000402 0.28210 0.01024 1.00000 0 55.90014 0.95601 50.80801 0.86893 15.76932 0.50476 14.33294 0.45879 58126.763284 0.000385 0.29885 0.01120 1.00000 0 54.16260 0.96459 49.23962 0.87692 16.18656 0.53360 14.71531 0.48510 58126.764095 0.000425 0.26090 0.00955 1.00000 0 56.45721 0.93059 51.31748 0.84587 14.72985 0.48151 13.38896 0.43767 58126.764925 0.000405 0.27790 0.01009 1.00000 0 56.34249 0.95322 51.20668 0.86633 15.65769 0.50305 14.23045 0.45720 58126.765741 0.000411 0.27718 0.01011 1.00000 0 55.57887 0.94436 50.51537 0.85833 15.40541 0.49729 14.00170 0.45197 58126.766577 0.000425 0.26462 0.00982 1.00000 0 55.19002 0.92359 50.15764 0.83937 14.60456 0.48399 13.27286 0.43985 58126.767526 0.000524 0.27696 0.00894 1.00000 0 56.17997 0.84101 51.05021 0.76422 15.55980 0.44486 14.13893 0.40424
