/* ** ** 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 58912.103978 0.000373 0.15468 0.01178 0.97674 0 22.73648 0.62776 20.62464 0.56945 3.51689 0.24962 3.19066 0.22646 58912.104710 0.000359 0.15825 0.01216 1.00000 0 22.64685 0.64318 20.45804 0.58102 3.58378 0.25596 3.23689 0.23118 58912.105421 0.000353 0.15890 0.01221 1.00000 0 22.61122 0.64720 20.53153 0.58767 3.59289 0.25631 3.26243 0.23273 58912.106139 0.000365 0.16123 0.01248 0.97619 0 22.18444 0.63390 19.96008 0.57032 3.57675 0.25739 3.21435 0.23134 58912.106880 0.000376 0.14956 0.01149 0.99231 0 22.66768 0.62641 20.57280 0.56851 3.39028 0.24292 3.07512 0.22034 58912.107673 0.000417 0.12994 0.00990 1.00000 0 23.59532 0.61030 21.18790 0.54798 3.06596 0.21968 2.75479 0.19739 58912.108428 0.000339 0.16321 0.01270 0.98291 0 23.40001 0.67411 21.11123 0.60815 3.81907 0.27594 3.44974 0.24919 58912.109134 0.000367 0.15388 0.01196 1.00000 0 22.24817 0.62930 20.19915 0.57135 3.42346 0.24794 3.10801 0.22510 58912.109860 0.000359 0.15616 0.01195 1.00000 0 22.74764 0.64231 20.65875 0.58332 3.55219 0.25276 3.22596 0.22955 58912.110543 0.000324 0.17147 0.01322 1.00000 0 22.93355 0.68084 20.82908 0.61836 3.93235 0.27981 3.57160 0.25414 58912.111229 0.000362 0.15830 0.01213 1.00000 0 22.37268 0.63690 20.21774 0.57552 3.54162 0.25203 3.20015 0.22771 58912.111926 0.000336 0.16969 0.01328 1.00000 0 22.08342 0.65555 20.05207 0.59525 3.74744 0.27141 3.40273 0.24644 58912.112635 0.000373 0.15115 0.01162 0.99225 0 22.57920 0.62851 20.50429 0.57076 3.41276 0.24454 3.09914 0.22206 58912.113451 0.000443 0.16436 0.01128 0.99346 0 22.16569 0.57583 20.12840 0.52291 3.64324 0.23146 3.30834 0.21018
