/* ** ** 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 58516.479249 0.000495 0.35622 0.05939 0.97661 0 2.37298 0.20599 1.68824 0.14649 0.84530 0.12034 0.59671 0.08488 58516.480219 0.000475 0.35621 0.06028 0.96341 0 2.30496 0.20160 1.75105 0.15314 0.82105 0.11894 0.62088 0.08990 58516.481127 0.000434 0.40899 0.06968 0.94000 0 2.23969 0.20412 1.71028 0.15587 0.91601 0.13184 0.69940 0.10067 58516.481932 0.000370 0.44630 0.07741 0.97656 0 2.34136 0.23242 1.78665 0.17736 1.04494 0.14864 0.79720 0.11340 58516.482736 0.000434 0.37437 0.06299 0.98000 0 2.36090 0.20906 1.80094 0.15947 0.88384 0.12646 0.67437 0.09649 58516.483659 0.000489 0.35752 0.06018 0.98225 0 2.17930 0.19023 1.66226 0.14509 0.77913 0.11214 0.59407 0.08551 58516.484643 0.000495 0.39281 0.06647 0.97661 0 1.98344 0.17918 1.51102 0.13650 0.77912 0.11148 0.59361 0.08494 58516.485499 0.000362 0.53163 0.09408 0.97600 0 2.01986 0.20981 1.54302 0.16027 1.07382 0.15386 0.82051 0.11757 58516.486237 0.000376 0.47101 0.08104 0.97692 0 2.21141 0.21598 1.69056 0.16511 1.04159 0.14754 0.79635 0.11280 58516.487157 0.000544 0.33407 0.05549 0.97872 0 2.10635 0.17460 1.60541 0.13308 0.70367 0.10128 0.53596 0.07714 58516.488115 0.000414 0.42784 0.07346 0.97203 0 2.20041 0.20876 1.66026 0.15751 0.94142 0.13471 0.71319 0.10205 58516.489391 0.000862 0.39332 0.04934 0.95973 0 2.11077 0.14208 1.60652 0.10814 0.83021 0.08787 0.63200 0.06689
