Notes. Check-marks or bold-font corresponds to a positive AGN classification. Entries with a hyphen correspond to sources which are outside the field-of-view of the bands required to classify the object or are not in the redshift range of the classification scheme. Blank entries have multi-wavelength coverage but do no have detections in all bands required. The column headers correspond to: (1) – VLBI source identifier as used in Paper I. (2) – Adopted redshifts from Paper I. Spectroscopic redshifts have no errors whilst errors on photometric redshifts correspond to 68% confidence intervals. (3) – Optical/NIR host galaxy morphologies classified into 1. early-type/bulge dominated, 2. late-type/spiral galaxies, 3. irregular, 4. Unclassified i.e., low surface brightness or unresolved. Potential evidence of interacting systems are marked with a *. (4) – Optical classification from Trouille et al. (2008). Optically normal galaxies (non-AGN) are classified as absorbers (A) or star-formers (SF). AGN are classified into high-excitation galaxies (HEG) or broad line AGN (BL). (5) Radio morphology classification from Muxlow et al. (2005) (AGN C – AGN candidate, S* – starburst + AGN). (6) – Radio variable sources as classified by Radcliffe et al. (2019a). (7) – Radio excess parameter using Spitzer MIPS 24 μm emission. (8) – Radio excess parameter using Herschel PACS 100 μm emission. (9) – Total radio excess parameter using rest-frame bolometric infrared luminosity and rest-frame 1.4 GHz flux density.

(a)

Blending effects from a bright infrared source around from the VLBI position prevents accurate 24 μm fluxes to be obtained.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
