Biases in the kinematic parallaxes of galactic planetary nebulae
It has recently been noted that the kinematic parallaxes of planetary nebulae(PNe) may be significantly in error. The pattern velocities of the shells, whichdetermine the lateral expansion of the outows, are likely to differ from line-ofsightvelocities determined through visual spectroscopy. It is u...
