/* ** ** 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 57550.825706 0.000252 0.17447 0.01370 1.00000 0 27.95810 0.83658 25.91571 0.77547 4.87782 0.35419 4.52167 0.32833 57550.826192 0.000234 0.18882 0.01458 0.97531 0 29.38401 0.90199 26.96544 0.82768 5.54831 0.39302 5.09941 0.36115 57550.826690 0.000263 0.17266 0.01358 1.00000 0 27.27055 0.81559 25.19150 0.75340 4.70840 0.34237 4.34694 0.31607 57550.827210 0.000258 0.17414 0.01360 0.98876 0 27.80573 0.83181 25.78888 0.77148 4.84219 0.34927 4.49098 0.32394 57550.827702 0.000234 0.19892 0.01562 0.98765 0 26.89954 0.86255 24.94850 0.79999 5.35093 0.38341 4.96283 0.35560 57550.828188 0.000252 0.18098 0.01423 0.96552 0 27.89988 0.84297 25.87614 0.78182 5.04942 0.36665 4.68316 0.34005 57550.828703 0.000263 0.15784 0.01240 1.00000 0 29.41602 0.84642 27.26568 0.78454 4.64295 0.33938 4.30291 0.31453 57550.829221 0.000255 0.17162 0.01332 0.98864 0 29.21834 0.86340 26.73006 0.78980 5.01458 0.35983 4.58865 0.32927 57550.829719 0.000243 0.18207 0.01433 1.00000 0 27.87409 0.85993 25.85258 0.79757 5.07506 0.36754 4.70701 0.34089 57550.830228 0.000266 0.17253 0.01323 0.98913 0 27.66575 0.81397 25.65915 0.75493 4.77316 0.33804 4.42696 0.31353 57550.830743 0.000249 0.17747 0.01405 1.00000 0 27.66133 0.84239 25.65560 0.78131 4.90903 0.35884 4.55308 0.33282 57550.831258 0.000266 0.17037 0.01347 0.97826 0 27.54668 0.81222 25.54908 0.75332 4.69308 0.34442 4.35276 0.31944 57550.831771 0.000246 0.18105 0.01402 1.00000 0 28.39075 0.86244 26.33183 0.79989 5.14009 0.36603 4.76732 0.33948 57550.832300 0.000284 0.15595 0.01186 0.98980 0 28.55714 0.80012 26.48649 0.74211 4.45350 0.31491 4.13059 0.29208 57550.832821 0.000237 0.18373 0.01440 0.98780 0 28.63226 0.87942 26.55607 0.81565 5.26054 0.37944 4.87908 0.35193 57550.833301 0.000243 0.18115 0.01436 0.98810 0 28.07945 0.86235 26.04346 0.79982 5.08646 0.37181 4.71765 0.34485 57550.833813 0.000269 0.16711 0.01284 1.00000 0 27.80868 0.81743 25.79209 0.75815 4.64722 0.32995 4.31021 0.30603 57550.834340 0.000252 0.18058 0.01411 1.00000 0 27.26037 0.82979 25.28357 0.76962 4.92259 0.35415 4.56562 0.32847 57550.834855 0.000263 0.16895 0.01334 1.00000 0 27.45975 0.81976 25.46878 0.76032 4.63929 0.33912 4.30291 0.31453 57550.835359 0.000240 0.18598 0.01462 1.00000 0 27.75618 0.86067 25.74360 0.79826 5.16216 0.37287 4.78786 0.34584 57550.835879 0.000281 0.15445 0.01182 1.00000 0 28.70358 0.80799 26.62204 0.74939 4.43332 0.31556 4.11182 0.29268 57550.836588 0.000428 0.19438 0.01117 0.99324 0 27.65245 0.64434 25.52063 0.59464 5.37501 0.28237 4.96188 0.26066
