/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 55310.294541 0.000391 0.34570 0.05703 0.95456 0 2.70667 0.22674 2.23704 0.18739 0.93569 0.13299 0.77391 0.10998 55310.296040 0.001108 0.47335 0.04100 0.98695 0 2.66717 0.13182 2.22697 0.11006 1.26252 0.08982 1.05419 0.07500 55310.297472 0.000324 0.50292 0.08425 0.97321 0 2.35331 0.22793 1.96527 0.19035 1.18353 0.16178 0.98847 0.13512 55310.298876 0.001079 0.51910 0.04572 0.96783 0 2.53971 0.13125 2.12165 0.10964 1.31837 0.09402 1.10141 0.07855 55310.300305 0.000350 0.43168 0.06807 0.96694 0 2.75664 0.24070 2.30134 0.20094 1.18999 0.15625 0.99311 0.13040 55310.301711 0.001056 0.49370 0.04289 0.97808 0 2.71048 0.13546 2.26359 0.11312 1.33816 0.09508 1.11742 0.07940 55310.303117 0.000350 0.37449 0.06314 0.96694 0 2.70358 0.23930 2.25547 0.19964 1.01246 0.14529 0.84493 0.12125 55310.303786 0.000318 0.40619 0.06900 0.94545 0 2.81614 0.25911 2.35081 0.21630 1.14388 0.16335 0.95474 0.13634 55310.305513 0.001409 0.46407 0.03576 0.97536 0 2.71794 0.11724 2.26241 0.09759 1.26133 0.08054 1.04995 0.06704
