Notes. The columns are marked as follows: (1) source name; (2) observation epoch; (3) morphological classification of the host galaxy: S – spiral, E – elliptical, L – lenticular, D – distorted ; (4) stellar mass; (5) stellar extinction, ‘0’ indicates a very small extinction value that the STARLIGHT program was unable to reliably estimate; (6) velocity dispersion; (7) log of the black hole mass; (8) log of the bolometric luminosity; (9) Eddington ratio; (10)/(11) BPT/WHAN classification.
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.
