Abstract:
    The distances of planetary nebulae (PNe) are still quite uncertain.
    Although observational estimates are available for a small proportion
    of PNe, based on statistical parallax and the like, such distances are
    very poorly determined for the majority of galactic PNe. In
    particular, estimates of so-called 'statistical' distance appear to
    differ by factors of ∼2.7. We point out that there is a well-defined
    correlation between the 5-GHz luminosity of the sources, L5, and
    their brightness temperatures, TB.
