/* ** ** 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 55588.137611 0.001002 0.54121 0.15021 0.98551 1 0.27168 0.04467 0.21765 0.03578 0.14704 0.03288 0.11765 0.02631 55588.139645 0.001031 0.38451 0.10192 1.00000 1 0.36414 0.05182 0.29236 0.04161 0.14002 0.03131 0.11268 0.02520 55588.141795 0.001118 0.49518 0.13562 0.98701 1 0.26656 0.04215 0.21334 0.03373 0.13200 0.02952 0.10526 0.02354 55588.144714 0.001801 0.37529 0.08827 0.98091 1 0.27486 0.03364 0.21821 0.02670 0.10315 0.02072 0.08189 0.01645 55588.201504 0.001670 0.32392 0.08340 0.99130 1 0.31091 0.03932 0.22231 0.02810 0.10071 0.02259 0.07018 0.01569 55588.204670 0.001496 0.48533 0.13260 0.98058 1 0.22879 0.03591 0.16321 0.02562 0.11104 0.02483 0.07921 0.01771 55588.208287 0.002121 0.45541 0.09916 0.96992 1 0.26619 0.03229 0.19081 0.02315 0.12123 0.02192 0.08701 0.01573 55588.268564 0.002048 0.40078 0.10641 0.98582 1 0.21954 0.03117 0.14360 0.02035 0.08799 0.01974 0.05755 0.01287 55588.274185 0.003573 0.46242 0.09110 0.98888 1 0.20460 0.02274 0.13416 0.01491 0.09461 0.01539 0.06232 0.01014
