    Hi,

    I don't see NeV3426 at ~8430A on VLT spectrum.
    Plobably in the Keck spectrum?

    Though I understand that this is not
    a straight explanation, but how about the
    following combinations?

    9179 Hbeta(4863-4853)
    8263 Hgamma(4342-4346)
    at z=0.90

    The latter wavelengths are from SDSS composite QSO
    spectra (D.Vanden Berk et al. AJ, 122, 549-564, 2001)
    I got this idea from Fig.6 of this paper
    when I tried to fit those two lines with
    SiIV and CIV (at z=4.92).

    The lines are not broad very much,
    but the line at 9179 seems to me slightly
    larger than velocity rotation/dispersion
    of usual galaxies. There might be weak
    broad-line components in this galaxy.

    The both photo-z codes give z=0.8 for this galaxy.

    Do we see [OIII] at 9510? Mmm...
