Notes. Spectra are integrated within a 400 × 400 pc 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 Brγ, H2 1−0S(1) and [FeII] 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.

(‡)

The Brγ peak of emission does not coincide with the stellar nucleus of the object but with the region we have adopted as the “nucleus” (see the main text for a further explanation).
