Description:
We present new spectroscopic data (43 objects) and derived plasma
diagnostics and abundances (164 objects) of a sample of planetary
nebulae in the direction of the Galactic center.
The spectra were obtained in July 2000 with the 1.9-m telescope at the
South African Astronomical Observatory. The spectral coverage was
3500-7000Å with an average resolution of 1000.

Note on table3.txt: In this table, there are three rows for each object, and a
fourth row used to separate the objects. The first row gives the values of
parameters computed from the nominal values of the observational data.
The second and third row give the upper and lower limits respectively of these
parameters as derived taking into account the observational error bars.
