Scientific paper

The spectroscopic study of about 400 southern planetary nebulae observed from 1984 to 1986 with the IDS system at the European Southern Observatory is reported. Line intensities relative to H-beta = 100 are given in the spectral range 400-700 nm for a selection of nebulae showing a number of lines sufficient for plasma analysis. A numerical code interprets the spectra by using the lines as plasma diagnostics; the excitation class, reddening correction, electron temperature and density are computed for the 93 selected nebulae.
