/* ** ** 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 57756.153586 0.000278 0.21548 0.01710 0.98958 0 21.15209 0.70194 19.31372 0.64094 4.55786 0.32855 4.15859 0.29968 57756.154144 0.000281 0.20948 0.01652 1.00000 0 21.39775 0.70392 19.64761 0.64635 4.48235 0.32134 4.11415 0.29495 57756.154694 0.000269 0.21768 0.01711 1.00000 0 21.63216 0.72056 19.88114 0.66223 4.70885 0.33515 4.32770 0.30802 57756.155281 0.000318 0.17594 0.01357 0.98182 0 22.89954 0.68024 21.04439 0.62513 4.02887 0.28686 3.70250 0.26362 57756.155903 0.000304 0.17835 0.01407 1.00000 0 22.79549 0.69429 20.94657 0.63798 4.06558 0.29578 3.73586 0.27179 57756.156485 0.000278 0.22091 0.01727 0.98958 0 20.90838 0.69893 19.21544 0.64234 4.61897 0.32651 4.24498 0.30008 57756.157044 0.000281 0.21501 0.01702 0.98969 0 21.21017 0.70408 19.37430 0.64313 4.56047 0.32765 4.16329 0.29911 57756.157654 0.000330 0.18270 0.01423 0.97368 0 21.27326 0.64714 19.54970 0.59471 3.88672 0.27876 3.57177 0.25617 57756.158296 0.000312 0.19811 0.01522 1.00000 0 20.88692 0.65989 19.08813 0.60302 4.13785 0.28972 3.78408 0.26494 57756.158936 0.000327 0.17228 0.01332 0.99115 0 22.69454 0.67204 20.62918 0.61088 3.90989 0.27912 3.55238 0.25358 57756.159552 0.000289 0.20802 0.01666 1.00000 0 20.54922 0.68156 18.88641 0.62641 4.27458 0.31165 3.92868 0.28643 57756.160137 0.000295 0.18789 0.01445 0.99020 0 23.57322 0.72225 21.38830 0.65527 4.42908 0.31231 4.01264 0.28295 57756.160718 0.000286 0.21351 0.01658 0.96970 0 21.86897 0.71119 19.61658 0.63794 4.66917 0.32935 4.19448 0.29586 57756.161320 0.000315 0.18650 0.01462 0.99083 0 21.55280 0.66528 19.60312 0.60504 4.01966 0.28964 3.65802 0.26361 57756.161971 0.000336 0.17817 0.01386 0.97414 0 21.65766 0.65307 19.68191 0.59349 3.85872 0.27677 3.50855 0.25164 57756.162602 0.000295 0.19780 0.01548 0.97059 0 22.58459 0.70919 20.51171 0.64404 4.46717 0.32013 4.05736 0.29075 57756.163158 0.000260 0.22942 0.01815 0.98889 0 21.67676 0.74107 19.60372 0.67014 4.97317 0.35482 4.49969 0.32108 57756.163675 0.000258 0.22450 0.01767 1.00000 0 22.15862 0.75069 20.13149 0.68196 4.97471 0.35341 4.51543 0.32069 57756.164260 0.000327 0.19381 0.01440 1.00000 0 22.12346 0.66365 20.11046 0.60324 4.28769 0.29148 3.89858 0.26502
