Abstract:                                ! Free format text (please update)
    We propose to study the emission line profiles of all high
    quality, low to intermediate redshift quasars in the  HST
    archive. This sample now makes it possible to do detailed
    analyses using both optical and UV spectra in the same
    objects. We will deblend lines and construct line profile
    ratios to determine line intensity ratios as a function of
    velocity. This will permit a photoionization analysis of the
    emitting regions as a function of velocity rather than from
    much less meaningful integrated fluxes. The high ionization
    blue-shifting effect will be studied, taking advantage of the
    knowledge of the true rest frame redshift of the quasar gained
    from the optical lines. Among other things, we are
    particularly interested in the physical properties of the
    region producing the highest ionization lines and the degree
    to which the UV line producing clouds are optically thin. We
    will be performing two types of principal component analysis
    (PCA) on the  HST spectra, a parametrized PCA and an
    unparametrized PCA to investigate object to object variations
    and their causes. We will be seeking particularly to verify
    our proposed connection between the main optical and UV
    principal components and the physical interpretation of some
    components.  We will attempt to derive the reddening of the
    BLR from line ratios and derive de-reddened line profile
    ratios. We will investigate abundances using information from
    both the UV lines and from the optical narrow lines (NLR) and
    investigate the correlation between the two.
