/* ** ** 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 56745.058384 0.000310 0.14701 0.01126 1.00000 0 28.54185 0.78476 25.34201 0.69679 4.19596 0.29990 3.72903 0.26654 56745.058983 0.000289 0.16492 0.01278 1.00000 0 27.36386 0.79501 24.29844 0.70580 4.51284 0.32432 4.01353 0.28847 56745.059527 0.000255 0.18730 0.01492 1.00000 0 26.50339 0.83326 23.88536 0.75095 4.96413 0.36346 4.47366 0.32755 56745.060085 0.000298 0.16146 0.01246 0.99029 0 27.07996 0.77751 24.12500 0.69269 4.37243 0.31331 3.89219 0.27892 56745.060646 0.000263 0.17604 0.01375 1.00000 0 27.62298 0.84032 24.81267 0.75476 4.86287 0.34988 4.36456 0.31405 56745.061202 0.000292 0.15345 0.01211 1.00000 0 28.38603 0.80813 25.16415 0.71642 4.35575 0.32058 3.85817 0.28401 56745.061783 0.000289 0.15185 0.01181 1.00000 0 29.08011 0.82253 26.01901 0.73591 4.41591 0.31983 3.95343 0.28638 56745.062377 0.000304 0.15788 0.01199 1.00000 0 27.23084 0.76917 24.54138 0.69320 4.29921 0.30298 3.87475 0.27307 56745.062950 0.000269 0.16491 0.01292 0.98925 0 28.74257 0.84397 25.92447 0.76122 4.74008 0.34426 4.27543 0.31052 56745.063479 0.000260 0.17578 0.01364 1.00000 0 27.99759 0.84746 25.22075 0.76340 4.92143 0.35178 4.43341 0.31689 56745.064020 0.000281 0.16850 0.01359 0.94845 0 27.50254 0.80915 24.78347 0.72916 4.63425 0.34812 4.17587 0.31369 56745.064582 0.000281 0.15683 0.01237 0.98969 0 29.02906 0.83347 25.99381 0.74627 4.55275 0.33431 4.07999 0.29953 56745.065146 0.000284 0.15064 0.01159 1.00000 0 29.83098 0.83336 26.89069 0.75122 4.49387 0.32204 4.05105 0.29030 56745.065704 0.000275 0.16065 0.01248 0.98947 0 29.24322 0.84183 26.19494 0.75406 4.69789 0.33887 4.20395 0.30328 56745.066248 0.000269 0.16481 0.01324 1.00000 0 28.52927 0.84907 25.18038 0.74940 4.70180 0.35090 4.15066 0.30969 56745.066804 0.000286 0.16377 0.01260 0.98990 0 27.71911 0.80133 24.98616 0.72232 4.53965 0.32366 4.09194 0.29174 56745.067348 0.000258 0.17404 0.01343 1.00000 0 29.07836 0.87164 26.00818 0.77943 5.06081 0.35994 4.52824 0.32203 56745.067883 0.000278 0.15333 0.01185 1.00000 0 30.30160 0.85375 26.96998 0.75980 4.64613 0.33444 4.13724 0.29770 56745.068407 0.000246 0.17313 0.01353 1.00000 0 29.80221 0.89572 26.85283 0.80708 5.15957 0.37222 4.64907 0.33540 56745.068925 0.000272 0.16945 0.01340 1.00000 0 27.60675 0.82548 24.71760 0.73909 4.67793 0.34258 4.18811 0.30664 56745.069547 0.000350 0.17840 0.01198 1.00000 0 27.43096 0.72064 24.59425 0.64608 4.89376 0.30252 4.39030 0.27138
