/* ** ** Swift/XRT hardness ratio for 3C 279. ** 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 54963.875249 0.001438 0.36951 0.09433 1.00000 1 0.28752 0.03809 0.23030 0.03050 0.10624 0.02319 0.08485 0.01852 54963.878024 0.001336 0.32659 0.08441 0.97603 1 0.33892 0.04391 0.27244 0.03530 0.11069 0.02475 0.08909 0.01992 54963.941863 0.001394 0.34336 0.08889 0.97917 1 0.30671 0.04000 0.24799 0.03234 0.10531 0.02355 0.08511 0.01903 54963.944550 0.001293 0.39365 0.10398 0.98876 1 0.28549 0.04015 0.23089 0.03247 0.11238 0.02513 0.09091 0.02033 54963.947121 0.001278 0.36139 0.09414 0.96591 1 0.32214 0.04305 0.26047 0.03481 0.11642 0.02603 0.09412 0.02105 54963.949300 0.000901 0.50441 0.13873 0.98387 1 0.32143 0.05147 0.26000 0.04163 0.16213 0.03625 0.13115 0.02933 54963.951828 0.001627 0.29648 0.07394 0.99291 1 0.31488 0.03803 0.25480 0.03077 0.09336 0.02037 0.07554 0.01648
