/* ** ** 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 58884.405931 0.000694 0.11396 0.00869 0.97083 0 16.78440 0.40413 14.86175 0.35782 1.91274 0.13837 1.69177 0.12239 58884.407325 0.000700 0.11193 0.00851 0.98760 0 16.68410 0.40023 14.81233 0.35534 1.86740 0.13473 1.65768 0.11961 58884.408743 0.000718 0.10740 0.00824 0.98790 0 16.82015 0.39646 14.93606 0.35204 1.80642 0.13183 1.60385 0.11705 58884.410161 0.000700 0.10941 0.00835 0.99174 0 16.88139 0.40090 15.02567 0.35683 1.84706 0.13404 1.64402 0.11930 58884.411550 0.000689 0.11656 0.00880 0.96639 0 16.65491 0.40265 14.82404 0.35839 1.94135 0.13885 1.72793 0.12358 58884.413390 0.001152 0.13405 0.00738 0.97990 0 16.52615 0.31098 14.68762 0.27639 2.21531 0.11466 1.96910 0.10191
