/* ** ** 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 56793.197671 0.001162 0.56771 0.15970 0.96250 1 0.22741 0.03844 0.18182 0.03073 0.12911 0.02903 0.10336 0.02324 56793.200343 0.001511 0.40428 0.10734 0.99038 1 0.23786 0.03406 0.19175 0.02745 0.09616 0.02150 0.07767 0.01737 56793.203336 0.001482 0.28619 0.07304 0.99020 1 0.34054 0.04113 0.27517 0.03323 0.09746 0.02191 0.07880 0.01772 56793.256038 0.001191 0.57036 0.15680 0.98780 1 0.22424 0.03749 0.18176 0.03038 0.12790 0.02791 0.10370 0.02263 56793.258304 0.001075 0.35884 0.09386 0.98649 1 0.37803 0.05128 0.30384 0.04121 0.13565 0.03033 0.10959 0.02450 56793.260933 0.001554 0.61365 0.14899 0.98206 1 0.21446 0.03249 0.17344 0.02628 0.13161 0.02497 0.10619 0.02015
