/* ** ** 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 58522.450149 0.000373 0.38586 0.06440 0.96124 0 2.46232 0.21817 2.09031 0.18518 0.95011 0.13437 0.80780 0.11424 58522.450971 0.000448 0.36771 0.06042 0.98065 0 2.15161 0.18492 1.83197 0.15744 0.79116 0.11079 0.67217 0.09412 58522.451850 0.000431 0.36142 0.06010 0.97315 0 2.24077 0.19328 1.89737 0.16365 0.80986 0.11513 0.68761 0.09775 58522.452655 0.000373 0.40969 0.06901 0.97674 0 2.30648 0.21104 1.94367 0.17783 0.94494 0.13364 0.79497 0.11243 58522.453514 0.000486 0.30107 0.04930 0.95238 0 2.40749 0.18923 2.04991 0.16112 0.72482 0.10412 0.61737 0.08868 58522.454405 0.000405 0.41436 0.07085 0.97857 0 2.06104 0.19357 1.73619 0.16303 0.85400 0.12203 0.72439 0.10351 58522.455195 0.000385 0.36440 0.06133 0.97744 0 2.45192 0.21509 2.08404 0.18282 0.89348 0.12834 0.75984 0.10914 58522.455896 0.000315 0.44677 0.07650 0.96330 0 2.55574 0.24375 2.15001 0.20506 1.14184 0.16236 0.95983 0.13647 58522.456706 0.000495 0.30075 0.04956 0.97661 0 2.33025 0.18515 1.96035 0.15576 0.70083 0.10117 0.58872 0.08501 58522.457629 0.000428 0.39068 0.06583 0.95946 0 2.11107 0.18851 1.78456 0.15935 0.82475 0.11786 0.69888 0.09986 58522.458488 0.000431 0.35955 0.05945 0.97987 0 2.27113 0.19444 1.93112 0.16533 0.81658 0.11551 0.69346 0.09809 58522.459272 0.000353 0.38201 0.06515 0.99180 0 2.51237 0.22802 2.13085 0.19337 0.95975 0.13858 0.81253 0.11732 58522.460363 0.000738 0.36925 0.04472 0.99216 0 2.38596 0.15140 2.02745 0.12865 0.88102 0.09089 0.74858 0.07722
