/* ** ** 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 56268.417843 0.000312 0.08312 0.01259 1.00000 0 12.85308 0.53764 10.94617 0.45738 1.06830 0.15549 0.91063 0.13224 56268.419095 0.000940 0.11154 0.00843 0.99077 0 13.05683 0.31223 11.05618 0.26436 1.45642 0.10439 1.23301 0.08835 56268.420343 0.000307 0.08657 0.01309 0.99057 0 12.77561 0.54344 10.83383 0.46084 1.10600 0.16047 0.93665 0.13602 56268.421648 0.000998 0.10186 0.00780 0.98551 0 13.22938 0.30463 11.29758 0.26014 1.34750 0.09848 1.15169 0.08418 56268.422950 0.000304 0.07755 0.01298 0.98095 0 13.34318 0.56039 11.37066 0.47752 1.03472 0.16771 0.88420 0.14309 56268.424171 0.000917 0.10562 0.00806 0.98738 0 13.94184 0.32591 11.90323 0.27823 1.47253 0.10690 1.25684 0.09126 56268.425398 0.000310 0.08401 0.01270 0.97196 0 13.08499 0.54304 11.26081 0.46732 1.09924 0.15979 0.94565 0.13733 56268.427429 0.001722 0.10336 0.00593 0.99160 0 13.45916 0.23381 11.46220 0.19910 1.39109 0.07611 1.18444 0.06482
