/* ** ** 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 58807.113661 0.000460 0.13772 0.01072 0.99371 0 19.50595 0.52095 18.00974 0.48099 2.68641 0.19643 2.47798 0.18117 58807.114564 0.000443 0.15111 0.01152 0.99346 0 18.91476 0.52374 17.46385 0.48354 2.85817 0.20294 2.63711 0.18724 58807.115423 0.000417 0.16520 0.01272 1.00000 0 18.09280 0.53058 16.76551 0.49166 2.98898 0.21276 2.76971 0.19716 58807.116303 0.000463 0.14061 0.01057 0.99375 0 19.53578 0.51761 18.10068 0.47959 2.74696 0.19328 2.54512 0.17907 58807.117220 0.000454 0.14731 0.01142 1.00000 0 18.44760 0.50992 17.09422 0.47251 2.71754 0.19684 2.51817 0.18240 58807.118193 0.000518 0.13310 0.01022 1.00000 0 17.90063 0.47205 16.58744 0.43742 2.38248 0.17187 2.20771 0.15926 58807.119107 0.000396 0.17524 0.01359 0.99270 0 18.06746 0.54328 16.74205 0.50343 3.16618 0.22631 2.93391 0.20970 58807.120036 0.000532 0.13037 0.00987 0.98370 0 18.23963 0.46994 16.90149 0.43546 2.37798 0.16927 2.20352 0.15685 58807.121002 0.000434 0.14886 0.01148 1.00000 0 19.19899 0.53199 17.78858 0.49291 2.85792 0.20563 2.64788 0.19052 58807.121899 0.000463 0.14471 0.01130 0.99375 0 18.36455 0.50520 17.01546 0.46808 2.65760 0.19431 2.46240 0.18003 58807.122981 0.000619 0.14638 0.00977 0.98598 0 18.73234 0.43974 17.35814 0.40748 2.74195 0.17140 2.54080 0.15883
