/* ** ** 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 54982.069627 0.001380 0.50367 0.13819 0.98947 1 0.21097 0.03354 0.16935 0.02692 0.10626 0.02376 0.08511 0.01903 54982.074042 0.003036 0.42913 0.08583 0.99844 1 0.19910 0.02202 0.16084 0.01779 0.08544 0.01424 0.06901 0.01150 54982.136969 0.002063 0.35836 0.09152 1.00000 1 0.20297 0.02693 0.16492 0.02189 0.07274 0.01587 0.05916 0.01291 54982.141733 0.002702 0.30611 0.07845 0.98387 1 0.17633 0.02208 0.14279 0.01788 0.05398 0.01207 0.04372 0.00978 54982.146149 0.001714 0.46257 0.12595 0.97458 1 0.18458 0.02836 0.14981 0.02302 0.08538 0.01919 0.06921 0.01556 54982.211422 0.063559 0.30162 0.06551 0.04726 1 0.21957 0.02293 0.17809 0.01859 0.06623 0.01261 0.05377 0.01024
