Abstract
The table of planetary nebulae parameters contains the name, Perek-Kohoutek (PK) designation (galactic longitude and latitude, 1 and b, followed by discovery order) and accurate optical right ascensions (R.A.) and declinations (Dec.) in the epoch 1950.0 from Blackwell and Purton (1981) and Milne (1973, 1976). When accurate positions were not available, those with less precision were obtained from the Perek-Kohoutek (1967) catalogue and its supplements. The optical angular diameter, θ, heliocentric radial velocity, V r , expansion velocity, V e , flux density, S6cm at 6 cm wavelength, absolute flux in the Hβ line, F(Hβ), electron density, N e , electron temperature, T e , the B and V magnitudes of the central star, and the extinction constant, C, for the brightest planetary nebulae were obtained from Lang (1980) and Pottasch (1984).
