7 Conclusions

We obtained the radio flux densities and diameters for 64 new galactic bulge PNe with the Australia Telescope Compact Array.

1.

We have a larger ratio of larger PNe with angular diameters around 10$^{\prime\prime}$ and radio flux densities below 15 mJy, than in previous surveys. Our survey seems to have picked out the larger low surface brightness PNe which were missed in optical surveys to date.

2.

We calculated their distances according to the method presented in Van de Steene & Zijlstra (1995). The new galactic bulge PNe are mainly located around the galactic center, and closer to it than the previously known PNe.

3.

We calculated the E(B-V) extinction value based on the radio flux densities and the total H$\alpha$ flux values from imaging. Only 1 PN was detected with a E(B-V) value larger than 4. Generally speaking, when E(B-V) > 4.0 the galactic bulge PNe become undetectable in H$\alpha$.
