Co-added LETG/ACIS data from Williams et al. (2007) observations (blue crosses), and the best-fit model (red line) consisting of a spline continuum and a redshifted O VIII doublet Voigt profile with the redshift as a free parameter. The dotted vertical line indicates the expected wavelength of the O VIII centroid, that is, assuming the FUV redshift of z = 0.05405.
