/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 60048.471515 0.000552 0.40497 0.10709 0.97368 1 1.19366 0.16845 0.53303 0.07521 0.48339 0.10810 0.21622 0.04835 60048.472721 0.000654 0.40625 0.10813 1.00000 1 0.96262 0.13896 0.43637 0.06298 0.39107 0.08745 0.17778 0.03975 60048.473955 0.000581 0.36393 0.09539 1.00000 1 1.18264 0.16171 0.55137 0.07539 0.43039 0.09624 0.20000 0.04472 60048.475088 0.000552 0.43817 0.11860 0.97368 1 1.06310 0.16213 0.49143 0.07494 0.46581 0.10417 0.21622 0.04835 60048.476076 0.000436 0.49662 0.13750 1.00000 1 1.16829 0.18835 0.53460 0.08617 0.58020 0.13060 0.26506 0.05965 60048.476991 0.000479 0.49930 0.13866 1.00000 1 1.09570 0.17803 0.48146 0.07812 0.54708 0.12321 0.24096 0.05423 60048.478037 0.000566 0.42806 0.11457 0.97436 1 1.07769 0.15851 0.49093 0.07220 0.46132 0.10316 0.21053 0.04708 60048.479577 0.000973 0.45022 0.09324 0.96390 1 1.02021 0.11743 0.46621 0.05366 0.45932 0.07907 0.20984 0.03612
