/* ** ** 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 54960.535431 0.001148 0.44125 0.11813 0.97468 1 0.29515 0.04345 0.23591 0.03473 0.13023 0.02912 0.10390 0.02323 54960.537639 0.001060 0.47011 0.12840 0.97260 1 0.29987 0.04651 0.23883 0.03704 0.14097 0.03169 0.11210 0.02520 54960.540878 0.002179 0.34243 0.06383 0.98450 1 0.38307 0.03627 0.30697 0.02906 0.13118 0.02106 0.10536 0.01692 54960.601862 0.000930 0.54801 0.15294 0.96875 1 0.28898 0.04779 0.23362 0.03863 0.15837 0.03560 0.12837 0.02886 54960.603895 0.001104 0.42236 0.11066 1.00000 1 0.32096 0.04654 0.26189 0.03797 0.13556 0.02958 0.11053 0.02412 54960.605798 0.000799 0.58527 0.16071 0.98182 1 0.32734 0.05456 0.26667 0.04444 0.19158 0.04181 0.15556 0.03395 54960.608151 0.001554 0.55341 0.11534 0.96893 1 0.30764 0.03829 0.24999 0.03111 0.17025 0.02846 0.13850 0.02315 54960.669851 0.001540 0.27883 0.07075 0.97170 1 0.34871 0.04181 0.27918 0.03347 0.09723 0.02174 0.07767 0.01737 54960.672567 0.001177 0.43212 0.11306 0.98765 1 0.30673 0.04427 0.24304 0.03508 0.13254 0.02892 0.10500 0.02291 54960.675414 0.001670 0.36577 0.07351 0.98351 1 0.41150 0.04310 0.32711 0.03426 0.15051 0.02582 0.12024 0.02062
