J/A+AS/108/485 J/A+AS/108/485 PN distance scale G C M Van De Steene A A Zijlstra Astron. Astrophys. Suppl. Ser. 108 485 1994 1994A&AS..108..485V catalogs planetary nebulae: general We have proposed a statistical method to determine distances to planetary nebulae. The method is based on an empirical correlation between the radio-continuum brightness temperature and radius. Here we present a catalog of distance determinations calculated using this method.
