Abstract
In this paper we present the updated empirical radio surface-
brightness-to-diameter (?-D) relation for Galactic supernova remnants (SNRs)
calibrated using 110 SNRs with reliable distances. We apply orthogonal
fitting procedure and kernel density smoothing in the ? ? D plane and compare
the results with the latest theoretical ? - D relations derived from
simulations of radio evolution of SNRs. We argue that the best agreement
between the empirical and simulated ? ? D relations is achieved if the
mixed-morphology SNRs and SNRs of both, low brightness and small diameter,
are filtered out from the calibration sample. The distances to 5 newly
discovered remnants and 27 new candidates for shell SNRs are estimated from
our full and filtered calibration samples.
