/* ** ** 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 56752.986292 0.000813 0.66223 0.19187 1.00000 1 0.37394 0.06868 0.22222 0.04057 0.24763 0.05549 0.14286 0.03194 56752.987919 0.000813 0.51284 0.14226 1.00000 1 0.44923 0.07371 0.27854 0.04569 0.23038 0.05153 0.14286 0.03194 56752.989705 0.000973 0.46327 0.12308 1.00000 1 0.42733 0.06474 0.26955 0.04083 0.19797 0.04320 0.12537 0.02736 56752.991361 0.000683 0.52462 0.14187 0.95745 1 0.57046 0.09023 0.35556 0.05622 0.29928 0.06564 0.18578 0.04074 56752.992770 0.000726 0.79032 0.23988 1.00000 1 0.32318 0.06629 0.19917 0.04083 0.25542 0.05715 0.16000 0.03578 56752.994266 0.000770 0.48349 0.12968 1.00000 1 0.52274 0.08068 0.32308 0.04985 0.25274 0.05544 0.15774 0.03459 56752.995762 0.000726 0.53373 0.13735 0.99992 1 0.56797 0.08765 0.35745 0.05516 0.30314 0.06243 0.19043 0.03921
