Cumulative distribution functions of average 5.8 GHz surface brightness (left), flux density (middle), and angular radius (right) of G19 SNRs (red), the SNR candidates discovered in earlier studies (green), and the new SNR candidates identified in the GLOSTAR-VLA survey (gray). The average surface brightness is obtained by dividing the flux density by the angular area subtended by the object. All the properties presented here are as measured in the GLOSTAR-VLA data.
