Abstract

High (CES spectrograph + RETICON at the CAT telescope) and low (B&C spectrograph + CCD at the 2.2-m telescope) resolution spectra of selected, southern planetary nebulae allowed to obtain the Hα and [NII] emission line profiles and the nebular emission line intensities in the spectral range λλ3650-9400 A. The Hα and [N II] emission line parameters were derived following the procedure used by Sabbadin (Monthly Not. Roy. Astron. Soc., 209, 889, 1984) and Ortolani and Sabbadin (Astron. Astrophys. Suppl. Series, 62, 17, 1985). Table 1 contains the relevant data for eight nebulae of the sample.
