ADC_Keywords: Planetary nebulae ; Spectroscopy ; Abundances Keywords: stars: abundances - ISM: planetary nebulae: general - Galaxy: bulge - Galaxy: abundances Description: We present new plasma diagnostics and abundances of a sample of planetary nebulae located in the Galactic bulge (168 objects), the Galactic inner disk (61 objects) and in the LMC (110 objects).

Note on table1a.txt, table1b.txt and table1c.txt: In these tables, 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.

Note (1): Quality flags on derived parameters are defined as follows: + = error is smaller than the computed median error of the parameter for the entire PNe sample : = larger uncertainty but error not exceeding the 0.3dex limit ; = data rejected due to error superior to 0.3dex or large uncertainties arising from the ICFs - = parameter could not be derived
