An updated catalogue of 310 Galactic supernova remnants and their statistical properties

Abstract

A revised catalogue of 310 Galactic supernova remnants (SNRs) and some statistics on their properties are presented. 21 SNRs have been added to the catalogue since the previously published version from 2019, and 5 entries have been removed, as they have been identified as H ii regions. Also discussed are some basic statistics of the remnants in the catalogue, the selection effects that apply to the identification of Galactic SNRs and their consequences.
