/* ** ** 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 56320.305898 0.000903 0.11072 0.00850 0.98718 0 15.30209 0.37097 11.58139 0.28016 1.69419 0.12349 1.27721 0.09274 56320.307579 0.000778 0.11811 0.00906 0.98513 0 16.24986 0.40287 12.56501 0.31149 1.91926 0.13937 1.48446 0.10779 56320.309110 0.000752 0.12509 0.00951 0.99231 0 15.58306 0.39577 12.30760 0.31255 1.94924 0.13968 1.53885 0.11026 56320.310629 0.000767 0.12106 0.00923 0.97358 0 16.13403 0.39911 12.64777 0.31285 1.95321 0.14085 1.53180 0.11049 56320.312143 0.000747 0.12198 0.00935 0.98837 0 16.04231 0.40320 12.73502 0.32005 1.95681 0.14167 1.55053 0.11229 56320.313627 0.000738 0.12722 0.01005 0.98039 0 15.46462 0.40357 12.13446 0.31658 1.96740 0.14672 1.54439 0.11518 56320.315516 0.001152 0.14049 0.00823 0.98995 0 15.90192 0.32486 12.50123 0.25535 2.23400 0.12258 1.75789 0.09642
