/* ** ** 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 58306.427777 0.000385 1.18492 0.05748 1.00000 0 13.78390 0.49313 12.39354 0.44339 16.33289 0.53505 14.68597 0.48110 58306.428566 0.000405 1.17882 0.05704 1.00000 0 13.39745 0.48186 11.94686 0.42965 15.79320 0.51123 14.08141 0.45581 58306.429385 0.000414 1.14367 0.05497 1.00000 0 13.41897 0.47582 12.02594 0.42638 15.34692 0.49790 13.74668 0.44595 58306.430196 0.000396 1.24876 0.06137 1.00000 0 12.86576 0.47596 11.52426 0.42635 16.06618 0.51977 14.38693 0.46541 58306.430985 0.000394 1.23904 0.06087 1.00000 0 13.05779 0.48076 11.69579 0.43062 16.17913 0.52620 14.48320 0.47104 58306.432018 0.000639 1.23912 0.04823 0.99608 0 12.78580 0.37366 11.50387 0.33619 15.84308 0.40732 14.25462 0.36649 58306.494513 0.000454 1.17360 0.05646 1.00000 0 12.76110 0.45529 10.69131 0.38146 14.97640 0.48329 12.55400 0.40508 58306.495430 0.000463 1.19291 0.05767 1.00000 0 12.29829 0.44371 10.36899 0.37406 14.67075 0.47200 12.37077 0.39795 58306.496321 0.000428 1.22535 0.05918 1.00000 0 12.99482 0.46955 10.98694 0.39700 15.92321 0.51026 13.46290 0.43142 58306.497198 0.000448 1.22965 0.06036 1.00000 0 12.22384 0.45005 10.29647 0.37904 15.03108 0.48801 12.65574 0.41086 58306.498477 0.000830 1.21202 0.04303 1.00000 0 12.69406 0.33607 10.59033 0.28038 15.38549 0.36390 12.83519 0.30357
