/* ** ** 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 59204.223137 0.000394 0.23021 0.01928 0.97794 0 23.83764 0.85860 12.50132 0.44359 5.48763 0.41501 2.94576 0.21719 59204.223927 0.000396 0.27677 0.02263 0.97810 0 21.82550 0.84176 10.75141 0.41423 6.04057 0.43558 2.97995 0.21477 59204.224719 0.000396 0.23971 0.01902 1.00000 0 23.63952 0.83646 12.24891 0.43324 5.66658 0.40238 2.92576 0.20775 59204.225489 0.000373 0.25239 0.02106 1.00000 0 24.17077 0.88722 12.04030 0.44199 6.10035 0.45715 3.04214 0.22786 59204.226276 0.000414 0.23794 0.01924 0.97902 0 23.26971 0.82468 11.80761 0.41834 5.53670 0.40241 2.80931 0.20407 59204.227095 0.000405 0.23746 0.01901 1.00000 0 23.61362 0.83528 11.98455 0.42389 5.60720 0.40269 2.85107 0.20465 59204.228333 0.000833 0.24597 0.01504 0.96570 0 20.66848 0.55534 10.34209 0.27785 5.08382 0.27912 2.54307 0.13967
