/* ** ** 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 57080.281427 0.000350 0.14905 0.01148 0.99174 0 24.34956 0.67013 22.11174 0.60854 3.62934 0.26095 3.29676 0.23703 57080.282118 0.000341 0.14450 0.01112 1.00000 0 25.75893 0.70224 23.40218 0.63799 3.72207 0.26776 3.38215 0.24331 57080.282763 0.000304 0.15978 0.01233 0.99048 0 26.46906 0.75631 23.92969 0.68370 4.22919 0.30328 3.82321 0.27418 57080.283423 0.000356 0.14749 0.01145 1.00000 0 23.83179 0.65989 21.66777 0.59997 3.51493 0.25485 3.19580 0.23171 57080.284141 0.000362 0.14521 0.01117 0.99200 0 24.17104 0.65941 21.97049 0.59937 3.50997 0.25236 3.19041 0.22939 57080.284960 0.000457 0.16621 0.01077 0.99608 0 23.82462 0.58431 21.66241 0.53128 3.95979 0.23758 3.60040 0.21602
