Notes. Values for refer to the heliocentric rest-frame corrected measurement, with the bracket notation reflecting the uncertainty in the profile-fit. θ is the angular separation between quasar and host, measured in arcsec from known photometry. θ is translated into an impact parameter (b) measured in kpc using the the spectroscopically determined emission-line redshift and the assumed cosmology.
refers to the nebular extinctions (SED, BDEC, SFR) derived from the χ2-minimising SED solution; the Balmer decrement; and based on the ratio of the SFR in Hα and [O II] under the assumption that they trace similar time-scales, respectively. Stellar mass estimates were determined from the maximum likelihood analysis of the SEDs χ2-distributions. The star-formation rate estimates were corrected for intrinsic and Galactic extinction, and were converted to a Chabrier IMF. σ corresponds to the velocity dispersion based on the profile fits to the emission lines after resolution correction using Eq. (1), and [O/H] to the preferred oxygen abundance derived from emission line ratios according to the M 08 prescriptions. [M/H]em refers to the metallicity in emission, inferred by applying a correction factor and truncation radius to the absorption metallicity.
Upper limit on EB−V imposed from dust-content priors (Sect. 3.6).
