/* ** ** 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 56025.922478 0.000871 0.16352 0.01291 0.97674 0 14.97933 0.44283 8.12187 0.23603 2.44941 0.17939 1.34164 0.09675 56025.924162 0.000813 0.17062 0.01330 0.97865 0 14.06136 0.41608 8.40151 0.24860 2.39916 0.17302 1.43434 0.10344 56025.925849 0.000874 0.15634 0.01197 0.97682 0 14.36763 0.40527 8.63281 0.24345 2.24622 0.15990 1.35116 0.09617 56025.927562 0.000839 0.15096 0.01161 0.98966 0 15.19150 0.42195 9.16679 0.25461 2.29325 0.16442 1.38496 0.09929 56025.929338 0.000938 0.14118 0.01080 0.98765 0 14.58672 0.39048 8.79473 0.23542 2.05930 0.14765 1.24214 0.08905 56025.931066 0.000790 0.16576 0.01281 0.97436 0 14.65183 0.42319 9.00076 0.25994 2.42872 0.17403 1.49067 0.10679 56025.932920 0.001065 0.17800 0.01191 0.97826 0 13.67356 0.35447 8.31193 0.21547 2.43383 0.15015 1.47985 0.09128
