/* ** ** 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 55642.519502 0.001380 0.40615 0.10760 0.97895 1 0.25907 0.03680 0.21191 0.03010 0.10522 0.02353 0.08602 0.01924 55642.521608 0.000726 0.66657 0.18867 0.98000 1 0.31791 0.05730 0.25750 0.04641 0.21191 0.04625 0.17143 0.03741 55642.523482 0.001148 0.46257 0.12575 0.96203 1 0.27742 0.04241 0.22579 0.03452 0.12833 0.02885 0.10473 0.02354 55642.526155 0.001525 0.35093 0.09121 0.99048 1 0.26971 0.03573 0.21923 0.02904 0.09465 0.02117 0.07692 0.01720 55642.528508 0.000828 0.78753 0.23466 0.96491 1 0.22537 0.04438 0.18500 0.03643 0.17749 0.03969 0.14546 0.03252 55642.530222 0.000886 0.59192 0.16829 1.00000 1 0.26751 0.04657 0.22000 0.03830 0.15835 0.03560 0.13049 0.02933 55642.533258 0.002150 0.40303 0.08344 0.98130 1 0.27508 0.03058 0.22482 0.02499 0.11087 0.01936 0.09061 0.01582
