Same as Fig. B.1, now for Δσ_⋆ against age. In general we argue that the three regions of each galaxy span little age range, which hinder the study of possible trends. The only exceptions are the three regions of NGC 1097 and the disc of NGC 1300. In the cases of the disc in NGC 1300 and the disc and nucleus in NGC 1097 we find vertical distributions, indicating the absence of any trend. For the ring in NGC 1097 we observe high mean values of Δσ_⋆ when compared with the typical error, but we do not find a clear distribution pattern, in addition to the fact that they present wide 1σ uncertainty intervals.
