/* ** ** 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 60065.416097 0.000738 0.15882 0.01225 0.96863 0 27.93273 0.79410 10.14212 0.28811 4.43639 0.31817 1.60634 0.11509 60065.417547 0.000712 0.15662 0.01215 0.97967 0 29.54454 0.84254 10.46423 0.29844 4.62734 0.33384 1.63677 0.11803 60065.419011 0.000752 0.15181 0.01186 0.98846 0 28.73175 0.81058 10.02934 0.28295 4.36180 0.31765 1.52280 0.11090 60065.420527 0.000764 0.15289 0.01191 0.98106 0 27.51944 0.77927 9.94292 0.28151 4.20736 0.30548 1.51803 0.11020 60065.422049 0.000758 0.13680 0.01072 0.98473 0 30.73842 0.82248 11.06267 0.29591 4.20498 0.30974 1.51155 0.11126 60065.423528 0.000720 0.15068 0.01158 0.97189 0 29.77044 0.82949 10.98748 0.30612 4.48582 0.32116 1.65801 0.11866 60065.424969 0.000720 0.14860 0.01147 0.98394 0 30.87373 0.84688 11.39598 0.31254 4.58781 0.33096 1.69143 0.12193
