/* ** ** 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 56437.382168 0.000741 0.45303 0.12218 0.98039 1 0.43861 0.06613 0.35200 0.05307 0.19870 0.04444 0.16000 0.03578 56437.383461 0.000552 0.47247 0.12998 1.00000 1 0.54834 0.08694 0.44331 0.07028 0.25907 0.05825 0.20945 0.04709 56437.384986 0.000973 0.43215 0.11710 1.00000 1 0.33784 0.05049 0.27211 0.04066 0.14600 0.03300 0.11819 0.02671 56437.387325 0.001365 0.24586 0.06143 1.00000 1 0.42972 0.04788 0.34751 0.03872 0.10565 0.02363 0.08511 0.01903 56437.389649 0.000959 0.52197 0.14335 0.90909 1 0.31579 0.05034 0.25609 0.04082 0.16483 0.03686 0.13333 0.02981 56437.391842 0.001206 0.43346 0.09606 0.96410 1 0.41181 0.04981 0.33510 0.04053 0.17850 0.03315 0.14496 0.02692
