Table 1: a) Measured line intensities, relative to I(C IV-5806) = 100, and FWHM (C IV-5806 and C III-5696) obtained for 42 WR CSPNe. The symbol "B'' indicates that the line results from a blend. The measured values for C IV-5806 are given in Col. 23 (units 10-15 ergs/cm2/s). All measurements are based on observations made at the 1.52 m telescope at ESO ( $\lambda \lambda $ 370-750 nm). Objects marked $^{\circ }$ were also observed at the 3.6 m telescope at ESO ( $\lambda \lambda $ 432-600 nm), the corresponding measurements are shown in italics. Objects marked * were observed at OHP ( $\lambda \lambda $ 510-600 nm). The symbol "(c)'' means that the line was detected by a visual inspection of plates obtained at the 1.52 m telescope + Chilicass at ESO, in Aug. 1972 (exposure time: 4h). The symbols ":'' and "vis'' mean respectively that the measurements are of poor quality, and that the line is visible but not measurable. The symbol "A'' refers to absorption features.
