/* ** ** 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 56643.881973 0.002179 0.25687 0.06551 0.99333 1 0.36836 0.04321 0.20387 0.02373 0.09462 0.02143 0.05316 0.01201 56643.885720 0.001569 0.39290 0.10490 0.99074 1 0.34945 0.05098 0.18990 0.02770 0.13730 0.03070 0.07477 0.01672 56643.888785 0.001496 0.43434 0.11774 1.00000 1 0.32108 0.04864 0.17698 0.02681 0.13946 0.03135 0.07729 0.01737 56643.891109 0.000828 0.81887 0.24614 0.94737 1 0.32821 0.06592 0.18110 0.03637 0.26876 0.06010 0.14815 0.03313 56643.893070 0.001133 0.50121 0.13825 1.00000 1 0.36555 0.05902 0.20370 0.03288 0.18322 0.04097 0.10257 0.02293 56643.896062 0.001859 0.35246 0.08978 0.98694 1 0.33153 0.04354 0.18812 0.02470 0.11685 0.02550 0.06649 0.01451 56643.938763 0.001177 0.30407 0.07839 0.98765 1 0.41101 0.05098 0.32500 0.04031 0.12498 0.02824 0.09901 0.02237 56643.940840 0.000901 0.70272 0.20607 0.98387 1 0.23298 0.04420 0.18601 0.03528 0.16372 0.03661 0.13115 0.02933 56643.943091 0.001351 0.42280 0.10112 0.95822 1 0.33267 0.04362 0.26638 0.03493 0.14065 0.02813 0.11222 0.02244
