/* ** ** 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 59668.015856 0.000981 0.10181 0.00766 0.98230 0 12.80264 0.29239 11.69419 0.26706 1.30348 0.09340 1.19228 0.08543 59668.017748 0.000911 0.10602 0.00809 0.98413 0 13.13668 0.30924 11.97501 0.28184 1.39269 0.10115 1.26900 0.09214 59668.019594 0.000935 0.10232 0.00790 0.99381 0 12.97261 0.30518 11.84556 0.27864 1.32731 0.09765 1.21417 0.08935 59668.021489 0.000961 0.10451 0.00791 0.97590 0 12.75496 0.29401 11.67847 0.26918 1.33297 0.09612 1.21978 0.08798 59668.023353 0.000903 0.10947 0.00830 0.98397 0 12.96103 0.30563 11.88841 0.28035 1.41884 0.10225 1.30097 0.09373 59668.025665 0.001409 0.11046 0.00663 0.99384 0 12.71409 0.24221 11.70287 0.22293 1.40434 0.07994 1.29217 0.07354
