/* ** ** 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 58140.508700 0.000414 0.43370 0.07335 0.99301 0 1.93418 0.18085 1.65351 0.15461 0.83886 0.11821 0.71566 0.10082 58140.509450 0.000336 0.57736 0.10413 1.00000 0 1.72323 0.18897 1.47934 0.16223 0.99493 0.14247 0.85409 0.12230 58140.510156 0.000370 0.53242 0.09345 0.96875 0 1.76691 0.18367 1.51719 0.15771 0.94073 0.13304 0.80780 0.11424 58140.510960 0.000434 0.37735 0.06390 0.96667 0 2.10118 0.18697 1.79610 0.15982 0.79288 0.11425 0.67950 0.09791 58140.511901 0.000506 0.37282 0.06222 0.97714 0 1.82970 0.15955 1.56625 0.13656 0.68214 0.09707 0.58258 0.08290 58140.512830 0.000422 0.33550 0.05520 0.99315 0 2.40562 0.20222 2.05968 0.17313 0.80709 0.11414 0.69081 0.09769 58140.513729 0.000477 0.36156 0.06063 0.96970 0 1.99457 0.17406 1.71265 0.14946 0.72115 0.10326 0.61921 0.08867 58140.514765 0.000558 0.30031 0.04947 0.98446 0 2.00962 0.16042 1.72719 0.13788 0.60352 0.08696 0.51857 0.07472 58140.515769 0.000434 0.37305 0.06334 0.98000 0 2.09291 0.18476 1.78879 0.15791 0.78076 0.11323 0.66654 0.09665 58140.516661 0.000457 0.46015 0.07925 0.97468 0 1.64525 0.16171 1.41356 0.13894 0.75707 0.10707 0.65043 0.09199 58140.517934 0.000816 0.36867 0.04564 0.96099 0 2.10457 0.13489 1.80797 0.11588 0.77589 0.08217 0.66666 0.07061
