/* ** ** 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 55232.717018 0.000307 0.40469 0.06876 0.98113 0 3.27089 0.29718 2.38218 0.21583 1.32369 0.19006 0.96229 0.13793 55232.718276 0.000952 0.53216 0.04695 0.98784 0 3.00343 0.15706 2.30037 0.12026 1.59830 0.11357 1.22799 0.08722 55232.720299 0.001071 0.46406 0.03986 0.96757 0 3.18309 0.15401 2.41117 0.11666 1.47713 0.10482 1.11893 0.07939 55232.722249 0.000880 0.49892 0.04358 0.98026 0 3.53711 0.17965 2.68827 0.13652 1.76472 0.12540 1.34247 0.09539 55232.724040 0.000911 0.49763 0.04328 0.96508 0 3.45515 0.17238 2.63445 0.13143 1.71939 0.12248 1.30938 0.09327 55232.725264 0.000312 0.39610 0.06544 0.99074 0 3.22951 0.28883 2.46419 0.22034 1.27919 0.17768 0.98253 0.13648 55232.726722 0.001146 0.40416 0.03428 0.97475 0 3.36004 0.15315 2.55578 0.11647 1.35801 0.09713 1.03347 0.07390 55232.729202 0.001334 0.49034 0.03599 0.98048 0 3.33410 0.14026 2.53633 0.10669 1.63483 0.09835 1.24369 0.07481
