Abstract:
Galactic planetary nebula (PN) distances are derived, except in a
small number of cases, through the calibration of statistical
properties of PNs. Such calibrations are limited by the accuracy of
individual PN distances, which are obtained with several
nonhomogeneous methods, each carrying its own set of liabilities. In
this paper we use the physical properties of the PNs in the Magellanic
Clouds and their accurately known distances to recalibrate the
Shklovsky/Daub (1982ApJ...260..612D 1982ApJ...260..612D) distance technique. Our new
calibration is very similar (within 1%) to the commonly used distance
scale by Cahn et al. (1992, Cat. J/A+AS/94/399), although there are
important differences. We present a catalog of Galactic PN distances
using our recalibration, which can be used for future applications,
and compare the best individual Galactic PN distances to our new and
several other distance scales, both in the literature and newly
recalibrated by us, finding that our scale is the most reliable to
date.
