Description:
    Spectrohotometric observations at high signal-to-noise ratio for a
    sample of 62 planetary nebulae are presented, together with the plasma
    and abundance analyses. The objects were selected homogeneously from
    the `Strasbourg-ESO Catalogue of Galactic Planetary Nebulae' by their
    height above the disk (over 300pc) and their Hβ surface
    brightness (between 10-12 and 10-14mW/m2/arcsec2).
    The abundances of O, S, Ar, and Cl are tighly correlated. The N/O
    ratio shows a wide range of values, independent of He or O abundance.

Note (1): For each nebula, the quality class (A, B, C) indicates
          the accuracy of the line intensities (see Table 1 in the paper)
Note (2): S: Saturated lines
          E: Intensities were taken from the Strasbourg-ESO survey spectra
           (catalogue V/84)
          I: Intensities were estimated from short exposure spectra taken
              immediately afterwards
          p: indicates lines that are present in the spectra, but too weak
              to be measured
