Notes. Both peak and integrated flux density values of our 1.6 GHz are displayed. The peak flux values are presented for the 4.8 GHz and 8.4 GHz measurements because the supernova SN 2008iz was resolved at these frequencies. The ΘR50% are the angular sizes derived as the radius of the supernova ring at 50% of the peak intensity on the outside of the bright rim.
