Notes. Spectra are integrated within a 2 × 2 kpc aperture, covering the nuclear region defined as the brightest spaxel in the K-band; the integrated emission of the FoV, defined as the integrated flux of those spaxels that contain at least the ≳90% of the total continuum flux in each band; and the peaks of the Paα and H2 1−0S(1) emission, centred on the brightest spaxel in each of the respective maps. The errors are obtained by a Monte Carlo method of N = 1000 simulations of each spectra.

(†)

Regions that are coincident with the nucleus of the object. The spectra are extracted and the lines are fitted independently.

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.
