/* ** ** 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 58813.239001 0.000362 0.14249 0.01104 1.00000 0 23.79570 0.64614 22.08883 0.59979 3.39057 0.24615 3.14741 0.22849 58813.239744 0.000382 0.13458 0.01027 0.97727 0 25.01322 0.65407 22.82787 0.59694 3.36640 0.24124 3.07788 0.22052 58813.240517 0.000391 0.13238 0.01007 1.00000 0 24.44785 0.63823 22.34381 0.58326 3.23651 0.23130 2.95593 0.21124 58813.241307 0.000399 0.12895 0.00986 0.97101 0 24.79921 0.63252 22.87813 0.58346 3.19775 0.23063 2.94953 0.21272 58813.242091 0.000385 0.12704 0.00982 1.00000 0 25.46439 0.65505 23.26985 0.59859 3.23494 0.23580 2.95955 0.21571 58813.242887 0.000411 0.12108 0.00934 1.00000 0 25.14939 0.63342 22.90374 0.57681 3.04520 0.22195 2.77197 0.20204 58813.243659 0.000362 0.13934 0.01072 0.98400 0 25.16288 0.67060 23.10707 0.61575 3.50624 0.25299 3.21331 0.23174 58813.244383 0.000362 0.13532 0.01051 0.97600 0 25.88048 0.68228 23.71108 0.62506 3.50205 0.25598 3.20997 0.23458 58813.245103 0.000359 0.14289 0.01099 0.98387 0 24.70800 0.66673 22.91505 0.61834 3.53041 0.25429 3.27407 0.23583 58813.245983 0.000521 0.13567 0.00898 0.99606 0 25.03662 0.55807 22.91849 0.51087 3.39666 0.21174 3.10911 0.19373
