/* ** ** 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 57156.474704 0.001380 0.35602 0.09253 0.95789 1 0.30687 0.04065 0.24783 0.03283 0.10925 0.02443 0.08791 0.01966 57156.477115 0.001031 0.42125 0.11261 0.98592 1 0.33530 0.04913 0.27131 0.03975 0.14124 0.03158 0.11429 0.02556 57156.479715 0.001569 0.31968 0.08290 0.98148 1 0.29033 0.03755 0.23490 0.03038 0.09281 0.02086 0.07510 0.01688 57156.483332 0.002048 0.40200 0.09174 0.96454 1 0.24323 0.02954 0.19681 0.02390 0.09778 0.01889 0.07912 0.01529 57156.675168 0.002600 0.33089 0.06888 0.97658 1 0.26573 0.02768 0.21312 0.02220 0.08793 0.01585 0.07071 0.01274 57156.874796 0.002251 0.31626 0.07762 0.98634 1 0.24250 0.02946 0.18107 0.02199 0.07669 0.01635 0.05756 0.01227
