/* ** ** 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 59728.905245 0.000333 0.15330 0.01177 0.99130 0 24.59251 0.68844 22.83035 0.63911 3.76993 0.26951 3.49979 0.25019 59728.905885 0.000307 0.15690 0.01215 1.00000 0 25.71815 0.73719 23.87899 0.68447 4.03506 0.29041 3.74650 0.26964 59728.906484 0.000292 0.16226 0.01254 1.00000 0 26.40454 0.76397 24.21279 0.70054 4.28447 0.30713 3.93042 0.28170 59728.907062 0.000286 0.17257 0.01348 0.98990 0 25.16351 0.75121 23.36412 0.69750 4.34241 0.31334 4.03190 0.29093 59728.907638 0.000289 0.16259 0.01264 0.99000 0 26.43847 0.76681 24.54777 0.71197 4.29857 0.31018 3.99117 0.28799 59728.908191 0.000263 0.17386 0.01362 1.00000 0 27.11498 0.82863 24.96021 0.76285 4.71434 0.34017 4.34204 0.31331 59728.908775 0.000321 0.15054 0.01179 0.99099 0 25.82854 0.72625 23.87804 0.67137 3.88818 0.28419 3.59631 0.26272 59728.909418 0.000321 0.13534 0.01061 1.00000 0 27.93069 0.75160 25.93317 0.69785 3.78009 0.27838 3.50977 0.25847 59728.910066 0.000327 0.13933 0.01077 1.00000 0 27.16136 0.73259 25.08189 0.67654 3.78452 0.27418 3.49807 0.25346 59728.910694 0.000301 0.15560 0.01223 1.00000 0 26.05583 0.74983 24.18857 0.69609 4.05437 0.29655 3.76376 0.27530 59728.911293 0.000298 0.16725 0.01291 1.00000 0 25.06873 0.74276 23.27612 0.68965 4.19283 0.29897 3.89300 0.27760 59728.911897 0.000307 0.15997 0.01270 1.00000 0 24.74504 0.73428 22.97534 0.68177 3.95842 0.29151 3.67532 0.27066 59728.912496 0.000292 0.15848 0.01212 0.99010 0 27.30158 0.77622 25.30552 0.71946 4.32665 0.30723 4.00823 0.28462 59728.913104 0.000315 0.14586 0.01135 1.00000 0 26.74306 0.74319 24.72108 0.68700 3.90077 0.28348 3.60806 0.26212 59728.913723 0.000304 0.16500 0.01285 0.99048 0 24.79864 0.72626 23.02537 0.67432 4.09188 0.29526 3.79929 0.27415 59728.914311 0.000284 0.16718 0.01296 1.00000 0 26.09555 0.77046 24.22940 0.71536 4.36273 0.31268 4.05074 0.29032 59728.914927 0.000333 0.14760 0.01135 1.00000 0 25.18872 0.70140 23.38756 0.65125 3.71778 0.26646 3.45194 0.24741 59728.915607 0.000347 0.14794 0.01086 1.00000 0 26.39257 0.70055 24.50529 0.65045 3.90450 0.26711 3.62530 0.24801
