/* ** ** Swift/XRT hardness ratio for 4U 1608-52. ** 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 58310.549250 0.001133 1.30269 0.14109 0.94872 1 3.32837 0.27176 0.83872 0.06848 4.33585 0.30856 1.09177 0.07770 58310.550703 0.000320 1.09292 0.22611 0.95455 1 3.52918 0.53189 0.88792 0.13382 3.85711 0.54665 0.97061 0.13756 58310.551356 0.000334 1.03496 0.21173 0.91304 1 3.77086 0.56109 0.94626 0.14080 3.90267 0.54796 0.97912 0.13747 58310.552010 0.000320 1.13682 0.23509 1.00000 1 3.36957 0.51839 0.84213 0.12956 3.83058 0.52936 0.95822 0.13242 58310.552649 0.000320 0.91883 0.18341 1.00000 1 4.01723 0.56466 1.00788 0.14166 3.69115 0.52317 0.92649 0.13131 58310.553390 0.000421 1.00333 0.20805 0.96552 1 2.86119 0.42825 0.71739 0.10738 2.87071 0.41199 0.71944 0.10326 58310.554334 0.000523 1.20303 0.22083 0.95099 1 2.82925 0.39424 0.70801 0.09866 3.40367 0.40672 0.85488 0.10214
