/* ** ** 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 59375.204863 0.000475 0.13423 0.01041 0.98171 0 19.57546 0.51043 18.13193 0.47277 2.62765 0.19184 2.43145 0.17751 59375.205853 0.000515 0.11944 0.00912 0.99438 0 20.09273 0.49907 18.64897 0.46318 2.39983 0.17333 2.22899 0.16100 59375.206863 0.000495 0.12900 0.00982 0.99415 0 19.50500 0.50003 18.15116 0.46532 2.51623 0.18032 2.34158 0.16780 59375.207870 0.000512 0.12173 0.00940 0.99435 0 19.63698 0.49300 18.27224 0.45873 2.39033 0.17451 2.22423 0.16238 59375.208842 0.000460 0.13504 0.01033 1.00000 0 19.82253 0.52162 18.44684 0.48542 2.67675 0.19231 2.49098 0.17897 59375.209776 0.000475 0.12958 0.00984 1.00000 0 20.10403 0.51846 18.70943 0.48250 2.60510 0.18617 2.42439 0.17326 59375.210723 0.000472 0.14184 0.01078 0.98160 0 18.89824 0.50634 17.58675 0.47120 2.68060 0.19055 2.49458 0.17733 59375.211666 0.000472 0.13023 0.00990 1.00000 0 20.12594 0.51968 18.72967 0.48362 2.62109 0.18732 2.43926 0.17432 59375.213003 0.000865 0.13613 0.00782 0.97993 0 18.89829 0.37280 17.58768 0.34695 2.57264 0.13880 2.39424 0.12917
