/* ** ** 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 55682.134390 0.000295 0.08107 0.01886 1.00000 0 5.39129 0.34661 4.84781 0.31163 0.43705 0.09773 0.39281 0.08784 55682.134989 0.000304 0.07160 0.01771 0.99048 0 5.66651 0.35210 5.08181 0.31575 0.40575 0.09714 0.36480 0.08735 55682.135629 0.000336 0.07598 0.01742 1.00000 0 5.51922 0.33138 4.98641 0.29939 0.41937 0.09280 0.37887 0.08383 55682.136289 0.000324 0.07185 0.01664 0.99107 0 5.56039 0.33571 5.02359 0.30330 0.39954 0.08934 0.36096 0.08071 55682.136992 0.000379 0.06137 0.01414 0.96947 0 5.69223 0.31689 5.14046 0.28618 0.34931 0.07811 0.31549 0.07054 55682.137886 0.000515 0.11207 0.01673 0.97753 0 5.68730 0.27194 5.13682 0.24562 0.63737 0.09014 0.57567 0.08141 55682.139130 0.000729 0.10428 0.01572 0.79367 0 5.26063 0.24524 4.75186 0.22152 0.54859 0.07864 0.49550 0.07103 55682.140371 0.000512 0.10865 0.01619 0.97740 0 5.89918 0.27672 5.32963 0.25001 0.64093 0.09064 0.57900 0.08188 55682.141176 0.000292 0.08161 0.01901 1.00000 0 5.38164 0.35127 4.86230 0.31737 0.43920 0.09821 0.39670 0.08870 55682.142105 0.000637 0.09475 0.01405 0.96364 0 5.56823 0.23932 5.03266 0.21630 0.52758 0.07486 0.47692 0.06767 55682.143268 0.000527 0.10355 0.01539 0.97802 0 6.01449 0.27431 5.43554 0.24790 0.62277 0.08807 0.56273 0.07958 55682.144414 0.000619 0.09679 0.01452 0.97196 0 5.44764 0.24181 4.92304 0.21853 0.52725 0.07558 0.47646 0.06830 55682.145611 0.000579 0.09426 0.01430 0.97000 0 5.93082 0.25973 5.36135 0.23479 0.55905 0.08123 0.50536 0.07343 55682.147052 0.000862 0.09784 0.01216 0.97987 0 5.50911 0.20423 4.97864 0.18456 0.53902 0.06397 0.48711 0.05781
