/* ** ** Swift/XRT hardness ratio for 3C 279. ** 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 54950.628359 0.000842 0.51836 0.14414 0.98276 1 0.33393 0.05464 0.26926 0.04405 0.17310 0.03892 0.13964 0.03139 54950.630058 0.000857 0.63903 0.18378 1.00000 1 0.26415 0.04777 0.21240 0.03841 0.16880 0.03775 0.13559 0.03032 54950.631728 0.000813 0.49703 0.13387 0.96429 1 0.38577 0.05968 0.31036 0.04801 0.19174 0.04227 0.15406 0.03396 54950.633326 0.000784 0.49188 0.13440 0.98148 1 0.38054 0.05974 0.30791 0.04834 0.18718 0.04186 0.15094 0.03375 54950.635447 0.001336 0.37093 0.08237 0.98540 1 0.41260 0.04810 0.33296 0.03882 0.15305 0.02893 0.12354 0.02335 54950.697145 0.000872 0.50189 0.13757 0.98333 1 0.33283 0.05277 0.27050 0.04288 0.16704 0.03735 0.13559 0.03032 54950.698742 0.000726 0.54460 0.15067 1.00000 1 0.37460 0.06262 0.30552 0.05107 0.20401 0.04497 0.16638 0.03668 54950.700761 0.001293 0.53007 0.12461 0.96901 1 0.30140 0.04214 0.24569 0.03435 0.15977 0.03019 0.12987 0.02454
