/* ** ** 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 57822.116978 0.001191 0.33119 0.08590 0.98780 1 0.36804 0.04760 0.29579 0.03826 0.12189 0.02740 0.09826 0.02209 57822.118968 0.000799 0.47811 0.13041 1.00000 1 0.37604 0.05873 0.30371 0.04743 0.17979 0.04020 0.14546 0.03252 57822.120551 0.000784 0.47074 0.12832 0.98148 1 0.39623 0.06178 0.31991 0.04988 0.18652 0.04171 0.15094 0.03375 57822.122178 0.000842 0.52031 0.14389 1.00000 1 0.33089 0.05383 0.26595 0.04327 0.17216 0.03850 0.13793 0.03084 57822.123659 0.000639 0.64248 0.18514 0.97727 1 0.35682 0.06431 0.28742 0.05180 0.22925 0.05154 0.18509 0.04161 57822.125330 0.001031 0.59117 0.13526 0.99454 1 0.36877 0.05227 0.29790 0.04222 0.21801 0.03916 0.17561 0.03154
