/* ** ** 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 58245.974262 0.000602 0.14318 0.01135 0.97596 0 18.51451 0.50475 13.40628 0.36451 2.65097 0.19725 1.91045 0.14160 58245.975448 0.000584 0.14486 0.01110 0.96535 0 18.12744 0.48791 14.13147 0.38037 2.62592 0.18849 2.04702 0.14692 58245.976547 0.000515 0.16310 0.01282 0.98876 0 17.60805 0.51697 13.70100 0.40226 2.87183 0.20940 2.23577 0.16305 58245.977661 0.000599 0.14012 0.01086 0.98068 0 17.79677 0.48085 13.83472 0.37375 2.49371 0.18119 1.93757 0.14073 58245.978773 0.000512 0.15278 0.01203 0.98870 0 18.68990 0.53112 14.65435 0.41641 2.85542 0.20967 2.23806 0.16432 58245.979846 0.000561 0.13775 0.01067 1.00000 0 18.82993 0.50682 14.71723 0.39614 2.59387 0.18842 2.02746 0.14726 58245.981053 0.000645 0.13576 0.01048 0.98206 0 16.94406 0.45226 13.28739 0.35463 2.30033 0.16668 1.80516 0.13077 58245.982855 0.001157 0.15011 0.00832 0.97250 0 17.13932 0.33811 13.37919 0.26392 2.57273 0.13323 2.00766 0.10395
