Notes. Specifically, rows give the following information: (1) rms sensitivity representative of the [CII] spectral region for a channel width of 30 km s−1, (2) average LAGN in the (sub-)sample, (3) average FIR-based SFR, (4) FWHM of the [CII] core, (5) average luminosity of the broad [CII] wings, (6) their significance, (7) FWHM, and (8) velocity shift. (9) Peak and (10) integrated flux density ratios of the broad [CII] with respect to the core [CII] emission.
( * ) Computed from the fit parameters errors, accounts for the uncertainty in modelling the narrow component.
( * *) Computed from the pure statistical uncertainty.
( * * * ) Computed as in ( * *), but excluding the central channels affected by the [CII] core.
