HST/COS Observations of Quasar Outflows in the 500-1050 \AA\ Rest Frame:
  V. Richness of Physical Diagnostics and Ionization Potential-dependent
  Velocity Shift in PKS J0352-0711
  We analyze absorption troughs from two outflows within PKS J0352-0711 (S1 at
$-$1950 km s$^{-1}$ and S2 at $-$3150 km s$^{-1}$) from spectra taken with
Hubble Space Telescope/Cosmic Origin Spectrograph, which cover the
diagnostic-rich 585-900 Angstrom rest frame wavelength range. In S2, for the
first time we clearly detect absorption troughs from Ca IV, Ca V, Ca V*, Ca
VII*, and Ca VIII*. The column density measurement of Ca V suggests S2 has a
super-solar metallicity. Both outflows require at least two ionization phases
where the column density of the very high-ionization phase is roughly 15 times
larger than the corresponding high-ionization phase. These high column
densities and very high-ionization potential ions are similar to X-ray warm
absorbers. The two phases of S2 show a unique velocity centroid shift between
associated troughs. Through Monte Carlo measurements of the O V* absorption
troughs, we determine the electron number density of S2 (fully corroborated by
independent measurements from the Ca V* and Ca VIII* troughs), yielding a
distance of 9 pc and a kinetic luminosity of 2$\times$10$^{43}$ erg s$^{-1}$.
S1 is located farther away at 500 pc from the central source with a kinetic
luminosity of 10$^{43}$ erg s$^{-1}$.
