/* ** ** 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 55562.419601 0.000356 0.09006 0.01347 1.00000 0 9.91472 0.42504 8.94902 0.38363 0.89295 0.12791 0.80610 0.11546 55562.420374 0.000417 0.07651 0.01137 0.98611 0 10.10958 0.39865 9.12595 0.35986 0.77353 0.11080 0.69824 0.10002 55562.421158 0.000367 0.09334 0.01382 1.00000 0 9.36285 0.40877 8.44952 0.36889 0.87397 0.12360 0.78872 0.11154 55562.421951 0.000425 0.07314 0.01126 0.97959 0 10.10790 0.39288 9.12438 0.35465 0.73933 0.11010 0.66737 0.09938 55562.422825 0.000448 0.07023 0.01054 1.00000 0 9.98602 0.38145 9.01405 0.34432 0.70134 0.10176 0.63312 0.09186 55562.423606 0.000333 0.09314 0.01378 0.99130 0 10.45109 0.45552 9.43495 0.41123 0.97341 0.13766 0.87866 0.12426 55562.424434 0.000495 0.06717 0.00981 0.97661 0 9.89180 0.36275 8.93089 0.32751 0.66439 0.09396 0.59980 0.08482 55562.425383 0.000454 0.07089 0.01037 0.96815 0 10.29780 0.38475 9.29659 0.34734 0.73001 0.10324 0.65899 0.09320 55562.426233 0.000396 0.07720 0.01148 1.00000 0 10.38220 0.41426 9.37471 0.37406 0.80155 0.11481 0.72372 0.10367 55562.427127 0.000498 0.06081 0.00897 0.99419 0 10.56128 0.37332 9.53479 0.33704 0.64221 0.09199 0.57983 0.08305 55562.428007 0.000382 0.09310 0.01377 0.97727 0 9.23882 0.40141 8.33976 0.36234 0.86011 0.12164 0.77649 0.10981 55562.428852 0.000463 0.07005 0.01025 0.98125 0 10.09212 0.37733 9.10858 0.34056 0.70692 0.09997 0.63801 0.09023 55562.429749 0.000434 0.06939 0.01041 0.99333 0 10.51698 0.39840 9.49113 0.35954 0.72980 0.10589 0.65862 0.09556 55562.430594 0.000411 0.07983 0.01174 0.97887 0 9.99361 0.40098 9.02722 0.36221 0.79780 0.11283 0.72062 0.10191 55562.431390 0.000385 0.08621 0.01286 0.96992 0 9.87377 0.40923 8.91558 0.36952 0.85127 0.12194 0.76861 0.11009 55562.432535 0.000761 0.07562 0.00818 0.97719 0 10.50643 0.30098 9.48362 0.27168 0.79448 0.08283 0.71715 0.07477
