Notes. - Column (2): PMAS type of 1D spectra. Column (3): linear physical size in kpc covered by the PMAS extraction apertures for the nuclear and integrated spectra using the distances given by Sanders et al. (2003) for the IRAS RBGS. Columns (4)-(7): observed (not corrected for extinction and/or stellar absorption) line ratios; * for NGC 7469 the line ratios correspond to the narrow components of the hydrogen recombination lines.
