/* ** ** 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 56038.985151 0.000385 0.09083 0.01341 0.98496 0 9.78508 0.41322 8.61041 0.36360 0.88881 0.12576 0.78227 0.11066 56038.985990 0.000454 0.07907 0.01116 0.98089 0 10.24989 0.38499 9.16411 0.34421 0.81051 0.11031 0.72497 0.09868 56039.026642 0.000373 0.08273 0.01265 0.96899 0 10.34234 0.42565 9.37764 0.38594 0.85564 0.12603 0.77586 0.11428 56039.027553 0.000538 0.12182 0.01377 0.96237 0 9.02781 0.33246 8.13235 0.29946 1.09976 0.11749 0.99014 0.10575 56039.028427 0.000336 0.10691 0.01592 0.98276 0 9.06354 0.42271 8.21894 0.38332 0.96895 0.13703 0.87865 0.12426 56039.029064 0.000301 0.11034 0.01689 0.98077 0 9.60535 0.46298 8.71094 0.41987 1.05990 0.15400 0.96121 0.13966 56039.029732 0.000367 0.09502 0.01425 0.98425 0 9.20027 0.40410 8.34340 0.36646 0.87425 0.12531 0.79284 0.11364 56039.030681 0.000582 0.10236 0.01217 0.97273 0 8.92735 0.31784 8.09630 0.28825 0.91379 0.10362 0.82872 0.09398 56039.049617 0.000388 0.09970 0.01499 0.98507 0 8.62509 0.39124 7.55480 0.34264 0.85994 0.12324 0.75091 0.10761 56039.050526 0.000521 0.12313 0.01448 0.96111 0 8.97391 0.34193 7.90218 0.30108 1.10499 0.12291 0.97169 0.10807 56039.051469 0.000422 0.08870 0.01360 0.96575 0 8.78229 0.37581 7.75854 0.33200 0.77897 0.11465 0.68815 0.10128 56039.052592 0.000700 0.09324 0.01062 0.97521 0 8.90796 0.29427 7.86966 0.25997 0.83054 0.09056 0.73371 0.08000
