/* ** ** 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 59940.230601 0.000284 0.13424 0.01035 1.00000 0 33.85849 0.89947 30.05132 0.79834 4.54531 0.32913 4.03494 0.29217 59940.231133 0.000249 0.15735 0.01200 1.00000 0 33.44561 0.94872 29.77071 0.84447 5.26252 0.37269 4.68444 0.33175 59940.231683 0.000301 0.12764 0.00989 1.00000 0 34.12201 0.88199 30.02436 0.77602 4.35550 0.31821 3.82695 0.27963 59940.232239 0.000255 0.15442 0.01197 0.98864 0 33.11336 0.93872 29.42633 0.83418 5.11342 0.36880 4.54290 0.32764 59940.232788 0.000295 0.12645 0.00979 0.99020 0 34.60908 0.88587 30.64613 0.78442 4.37617 0.31978 3.87732 0.28336 59940.233379 0.000295 0.12853 0.01002 0.98039 0 34.10573 0.87945 30.33636 0.78223 4.38364 0.32249 3.89798 0.28677 59940.233966 0.000292 0.12365 0.00938 0.99010 0 36.47318 0.91534 32.45040 0.81438 4.50993 0.32276 4.01242 0.28715 59940.234556 0.000298 0.12348 0.00938 0.99029 0 35.43924 0.89495 31.52515 0.79611 4.37588 0.31352 3.89259 0.27889 59940.235118 0.000263 0.14930 0.01136 1.00000 0 33.50255 0.92419 29.81488 0.82247 5.00184 0.35475 4.45118 0.31569 59940.235662 0.000281 0.13869 0.01066 1.00000 0 33.65268 0.90889 29.51766 0.79717 4.66718 0.33576 4.09521 0.29459 59940.236229 0.000286 0.14139 0.01079 1.00000 0 32.90476 0.88952 28.83153 0.77934 4.65248 0.33218 4.07319 0.29076 59940.236802 0.000286 0.13114 0.00998 0.96970 0 35.55278 0.91326 31.53273 0.81001 4.66236 0.33403 4.13587 0.29632 59940.237378 0.000289 0.12985 0.01015 1.00000 0 34.26556 0.90375 30.00115 0.79129 4.44951 0.32740 3.89798 0.28677 59940.237974 0.000307 0.12372 0.00944 1.00000 0 34.50763 0.87607 30.34006 0.77025 4.26934 0.30709 3.74751 0.26958 59940.238558 0.000278 0.14328 0.01112 1.00000 0 32.22146 0.88716 28.59721 0.78734 4.61679 0.33515 4.09813 0.29752 59940.239111 0.000275 0.13576 0.01057 1.00000 0 34.20882 0.91487 30.38104 0.81240 4.64435 0.33943 4.12220 0.30126 59940.239669 0.000284 0.13630 0.01049 1.00000 0 33.41615 0.89902 29.57236 0.79548 4.55476 0.32849 4.03298 0.29086 59940.240456 0.000503 0.13217 0.00764 0.99425 0 35.03577 0.68887 30.82945 0.60613 4.63055 0.25163 4.07344 0.22140
