larger number of PNe with low flux densities among the new bulge PNe than among the known ones. 67 % of the new PNe have a radio flux less than 15 mJy, while this is only 45 % for the known ones. Of the 7 known ones within 2 degrees of the galactic center only 2 have a radio flux below 15 mJy. The median flux for the new PNe is 11.3 mJy, while the median for the known bulge PNe is 17.0 mJy. Our rms noise level in the maps is similar to the 1 $\sigma$ noise of 0.1 mJy in the 6 cm maps of Zijlstra et al. ([@Zijlstra89]). Apparently these faint and small PNe have just been missed in optical surveys done to date.

Angular Size
------------

Table \[tabflux\] also gives the angular size of the detected PNe. We chose to determine the angular size at 6 cm because at this wavelength the resolution was lower and thus gives the best signal to noise ratio for the extended nebulae. The diameter at 3 cm is given if it is better determined than at 6 cm, such as for very small and bright PNe.
