/* ** ** 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 57733.211417 0.000385 0.10082 0.01515 0.98496 0 8.27806 0.37436 7.51034 0.33963 0.83463 0.11964 0.75648 0.10844 57733.212175 0.000373 0.09712 0.01461 0.96899 0 9.03889 0.39879 8.23989 0.36354 0.87787 0.12625 0.80028 0.11509 57733.212875 0.000327 0.12662 0.01905 1.00000 0 7.80317 0.40050 6.99673 0.35908 0.98800 0.13974 0.88643 0.12536 57733.213619 0.000417 0.11661 0.01532 0.99306 0 9.03926 0.37708 8.19649 0.34192 1.05408 0.13130 0.95734 0.11922 57733.214380 0.000344 0.11705 0.01731 0.96639 0 8.40141 0.39952 7.57763 0.36031 0.98343 0.13772 0.88844 0.12441 57733.215390 0.000666 0.12202 0.01212 0.99565 0 9.01474 0.29874 8.17111 0.27078 1.09999 0.10303 0.99729 0.09341 57733.216371 0.000315 0.12143 0.01893 0.98165 0 8.30844 0.42191 7.45304 0.37850 1.00890 0.14869 0.90621 0.13351 57733.217019 0.000333 0.11150 0.01666 0.95652 0 9.12052 0.42824 8.22739 0.38626 1.01697 0.14430 0.91912 0.13042 57733.217708 0.000356 0.10389 0.01564 0.97561 0 8.75844 0.40260 7.94277 0.36510 0.90990 0.13043 0.82583 0.11838 57733.218405 0.000341 0.11881 0.01824 0.98305 0 7.88156 0.39107 7.10823 0.35263 0.93643 0.13607 0.84510 0.12281 57733.219079 0.000333 0.11419 0.01703 0.95652 0 8.74904 0.41476 7.97439 0.37804 0.99908 0.14129 0.91061 0.12878 57733.219765 0.000353 0.12010 0.01661 0.99180 0 9.05140 0.41128 8.20442 0.37279 1.08711 0.14196 0.98457 0.12855 57733.220419 0.000301 0.12117 0.01862 0.98077 0 8.75570 0.43708 7.93044 0.39588 1.06091 0.15416 0.96110 0.13967 57733.221099 0.000379 0.09533 0.01430 0.97710 0 8.91029 0.39262 8.12134 0.35786 0.84942 0.12176 0.77421 0.11098 57733.221793 0.000315 0.11929 0.01769 0.97248 0 8.90968 0.43371 8.08086 0.39336 1.06287 0.14884 0.96387 0.13497 57733.222441 0.000333 0.12246 0.01840 0.97391 0 8.09139 0.40038 7.37264 0.36482 0.99083 0.14060 0.90270 0.12809 57733.223179 0.000405 0.10705 0.01561 0.98571 0 8.16374 0.36128 7.44074 0.32928 0.87393 0.12144 0.79653 0.11069
