The Σ-D relation for Galactic planetary nebulae: application of orthogonal fitting procedure
Abstract
We estimate the parameters of the radio surface brightness to diameter
(Σ-D) relation for the sample of Galactic planetary nebulae (PNe). The
bootstrap re-sampling and orthogonal offsets fitting procedure are applied. The orthogonal fitting procedure provides that the parameter values of
D-Σ and Σ-D fits are invariant within the estimated uncertainties. We
discuss the probability statistics of the fitted (log Σ = log A - β log D) relation and the resulting fit parameters which is indicative for
PN distance determination.
