/* ** ** 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 59371.165871 0.000663 0.12777 0.00975 0.99127 0 14.75525 0.37929 13.65633 0.35103 1.88525 0.13541 1.74505 0.12534 59371.167086 0.000553 0.15234 0.01170 0.99476 0 14.79688 0.41623 13.73834 0.38645 2.25409 0.16106 2.09284 0.14954 59371.168267 0.000628 0.13309 0.01014 0.99539 0 15.05484 0.39757 13.82334 0.36510 2.00363 0.14318 1.84093 0.13154 59371.169514 0.000619 0.13739 0.01042 0.98598 0 14.98715 0.39626 13.76105 0.36381 2.05905 0.14636 1.89172 0.13446 59371.170741 0.000608 0.13297 0.01033 1.00000 0 15.23281 0.40601 14.01416 0.37353 2.02550 0.14784 1.86469 0.13606 59371.171916 0.000567 0.14996 0.01179 1.00000 0 14.35203 0.40764 13.27363 0.37697 2.15221 0.15785 1.99016 0.14598 59371.173389 0.000906 0.15126 0.00907 0.98460 0 15.20079 0.33162 14.01163 0.30569 2.29930 0.12838 2.11902 0.11832
