/* ** ** 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 56589.507120 0.000886 0.80240 0.24233 0.98361 1 0.20529 0.04140 0.16534 0.03335 0.16473 0.03703 0.13267 0.02982 56589.508573 0.000566 2.80805 1.24872 0.97436 1 0.09257 0.03552 0.07460 0.02862 0.25995 0.05843 0.20948 0.04709 56589.509997 0.000857 0.70481 0.21099 0.98305 1 0.24164 0.04778 0.19472 0.03850 0.17031 0.03828 0.13724 0.03085 56589.511260 0.000407 1.09895 0.36374 1.00000 1 0.32268 0.07875 0.26001 0.06345 0.35461 0.07929 0.28572 0.06389 56589.512248 0.000581 1.51057 0.54081 0.97500 1 0.16849 0.04711 0.13579 0.03797 0.25452 0.05691 0.20513 0.04587 56589.513395 0.000566 1.50971 0.54050 0.97436 1 0.17352 0.04852 0.13946 0.03899 0.26197 0.05858 0.21053 0.04708 56589.514587 0.000625 1.23420 0.42251 1.00000 1 0.18615 0.04806 0.15000 0.03873 0.22974 0.05164 0.18512 0.04161 56589.516286 0.001075 1.42847 0.43467 0.96486 1 0.13141 0.03097 0.10588 0.02496 0.18771 0.03612 0.15126 0.02911
