cds-question@unistra.frsupernova-remnantsradio-sourcesstellar-agesstellar-radiistellar-distanceWe present a revised table of 390 Galactic radio supernova remnants (SNRs) and their basic parameters. Statistical analyses are performed on SNR diameters, ages, spectral indices, Galactic heights, and spherical symmetries. Furthermore, the accuracy of distances estimated using the {Sigma}-D relation is examined. The arithmetic mean of the Galactic SNR diameters is 30.5pc with standard error 1.7pc and standard deviation 25.4pc. The geometric mean and geometric standard deviation factor of Galactic SNR diameters is 21.9pc and 2.4, respectively. We estimate ages of 97 SNRs and find a supernova (SN) birth rate lower than, but within 2{sigma} of, currently accepted values for the SN birth rate. The mean spectral index of shell-type SNRs is -0.51+/-0.01 and no correlations are found between spectral indices and the SNR parameters of molecular cloud association, SN type, diameter, Galactic height, and surface brightness. The Galactic height distribution of SNRs is best described by an exponential distribution with a scale height of 48+/-4pc. The spherical symmetry measured by the ovality of radio SNRs is not correlated to any other SNR parameters considered here or to explosion type.2023ApJS..265...53Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/265/53CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/15 : Galactic Supernova Remnants Catalogue (Ilovaisky+ 1972)VII/14 : Galactic Supernova Remnants Catalogue (Clark+ 1976)VII/187 : A Catalogue of Galactic Supernova Remnants (Green 1995)VII/284 : A Catalogue of Galactic Supernova Remnants (Green, 2019)J/ApJS/73/781 : X-ray obs. of galactic Supernova Remnants (Seward, 1990)J/AJ/104/704 : VLA Search for Young Galactic SNRs (Sramek+, 1992)J/other/BSAO/46.62 : RATAN observations of Galactic SNRs (Trushkin+, 1998)J/A+A/508/1331 : CO maps of 3 galactic supernova remnants (Liszt, 2009)J/ApJS/187/495 : SNRs in M33 from optical and X-ray (Long+, 2010)J/ApJ/786/130 : Catalog of M31 SNR candidates (Lee+, 2014)J/MNRAS/437/1791 : RMS survey: molecular observations (Urquhart+, 2014)J/A+A/612/A3 : HESS Galactic supernova remnants (Hess+, 2018)J/A+A/651/A86 : GLOSTAR Galactic plane survey.
